  • To open this window.
  • If you are editing one joist, its member number (" Member xx ") is printed in the title bar, and the " Summary " lists other joists that have been assigned the same piecemark.
  • " Joist Edit - Multiple Members " is this window's title if you are editing multiple joists .
  • This window is mostly read-only and called Joist Review if the " Model complete date " is set and ' Restrictive ' is selected.
  • " Copy " " Paste " " Save " " Load " buttons (form buttons) are embedded in the headers for individual leaves on this window. They apply to the settings that are contained in that leaf. Some form buttons, such as those for [ Left end settings ] apply to multiple leaves. Click here ( ) for more information. " Paste " and " Load " replace mixed entries to a single field with a single entry. " Copy " and " Save " ignore fields with mixed entries, treating them as if they have no entry or do not exist. Form buttons above sections that have multiple subordinate leaves under them -- e.g., [ Left end settings ] or [ Right end settings ] -- operate on settings under all of the subordinate leaves. For example, if you wanted to copy a connection from the left end to the right end, you would use the " Copy " button under [ Left end settings ], then use the " Paste " button under [ Right end settings ]. Special case: Form buttons do not operate on " Piecemark " or "ABM Options ."
  • " Save " ( ) places a file (which you name) in a subfolder of the form/joist folder that is used by your current version of this program. The exact subfolder depends on where the button is located. " Load " ( ) takes you to that same folder.

Shape : Parallel or Single pitch or Double pitch or Arched chord or Bowstring or Scissor or Triple pitch or BIM custom .

VIDEO The " Shape " of several joists are changed in the model. (Recorded in SDS2 Detailing , v2017.)

VIDEO The " Shape " of a joist whose " Panel display method " is ' User pre-config ' is changed from ' Parallel ' to ' Single pitch ' to ' Double pitch ' to ' Arched chord ' to ' Bowstring ' to ' Scissor ' to ' Triple pitch '. (Recorded in SDS2 Detailing , v2017.)

' Parallel ' makes the top and bottom chords of the joist parallel with one another.

' Single pitch ' angles the bottom chord with respect to a horizontal top chord.

' Double pitch ' divides the top chord of the joist into two sections, each of which slope to a peak at or near the joist's center. The " Peak offset " sets the distance of the peak from the left end of the joist. The bottom chord is straight.

' Arched chord ' arches both the top and bottom chords of the joist. The " Top chord radius " sets the curvature of the top cord, which in turn sets the curvature of the bottom chord so that the same distance of separation is maintained between all corresponding points along the two chords. .

' Bowstring ' arches the top chord of the joist while the bottom chord stays straight. The " Top chord radius " sets the curvature of the top cord.

' Scissor ' makes both the top chord and the bottom chord of the joist come to a peak. The " Peak offset " sets the distance of that peak from the left end of the joist.

' Triple pitch ' divides the top chord into three different sections, each with a different pitch. The center section of the top chord is parallel with the bottom chord. The bottom chord is straight. The two outside sections of the top chord slope upward toward the center sect on.

' BIM custom ' is a shape that is provided by the " Joist manufacturer " that is selected at Home > Project Settings > Job > Joist Manufacturers . If a custom shape is not provided, a parallel joist shape will be generated.

Peak offset : The distance parallel with the joist's input work points (in the primary dimension " Units " or other units ) from the left end of the joist to the peak of the joist.

VIDEO The " Peak offset " is changed on ' Double pitch ' and ' Scissor ' joists. (Recorded in SDS2 Detailing , v2017.)

The " Peak offset " option is enabled ( not grayed out ) when ' Double pitch ' or ' Scissor ' is selected as the " Shape ." The joist shown here is a scissor joist. The left end of the joist is identified by an origin reference point symbol ( ).

For a ' Double pitch ' joist, the " Peak offset " positions the peak at the top chord. For a ' Scissor ' joist, as is shown in the example above, " Peak offset " positions the peaks at both the top and bottom chords.

Top chord radius : The distance (in the primary dimension " Units " or other units ) that any and all points on the top of the joist's top chord are from the center of a circle that circumscribes the top of the joist's top chord.

r = top chord radius. If you were to extrapolate a circle from the curvature of the joist's top chord, the distance from any point on that curve to the center of the circle is the distance entered here.

The " Top chord radius " option is enabled ( not grayed out ) when ' Arched chord ' or ' Bowstring ' is selected as the " Shape ."

Joist rotation : A positive (+) or negative (-) number of degrees.

The axis of rotation is a line through the input points of the joist, which are marked with an X . The " Input elevation " does not change when you rotate the joist. As shown in this example, the left-end top chord reference symbol ( ) stays vertically aligned with the left-end input point.

' 0 ' degrees orients the joist vertically, that is, so that it its web panel is vertical.

' A positive number ' of degrees rotates the joist clockwise from its zero position.

' A negative number ' of degrees rotates the joist counterclockwise from its zero position.

Panel display method : Automatic or Reserved or Mfg pre-config or User pre-config . The choice that is made here does not affect the joist's ability to connect to other members. The " Panel display method " only affects the appearance of the joist, not its functionality. With the exception of system connection materials, joist materials are dummy materials .

' Automatic ' applies the choice made to " Panel display method " at Home > Project Settings > Job > Joist Manufacturers .

' Reserved ' puts a flat plate layout as a placeholder at the approximate location where web material can be designed by a manufacturer.

' Mfg pre-config ' requires that the " Joist manufacturer " has provided BIM information for the joist. If the manufacturer has not provided such information, you get a warning -- after you press "OK" -- and the joist is displayed as if you had selected ' Reserved '.

VIDEO The " Panel display method " is set to ' Mfg pre-config ', but since the manufacturer has not provided valid panel configuration, the user gets a warning. (Recorded in SDS2 Detailing , v2017.)

' User pre-config ' provides an approximation of the joist panel. " User preconfigured panel " options on this window can be used to fine tune the appearance of this joist.

VIDEO The " Panel display method " is set to ' User configured panel ' and settings under " User preconfigured panel " are adjusted. The result is shown in the model. (Recorded in SDS2 Detailing , v2017.)

If you are using imperial " Units ," the " Bay pitch " is reported in in/ft. For metric " Units ," the " Bay pitch " it is reported in mm/250 mm.

VIDEO A joist whose both ends are at the same " Input elevation " has a " Bay pitch " of ' 0 '. The " Input elevation " of that joist is changed, resulting in its " Bay pitch " being reported as ' 15/16 in/ft '. (Recorded in SDS2 Detailing , v2017.)

  • If the left-end " Top of joist " elevation is greater than the right-end " Top of joist ," the " Bay pitch " is a negative number.
  • If the left- and right-end " Input " elevation are both the same, the " Bay pitch " is ' 0 '.
  • If the left-end " Top of joist " elevation is less than the right-end " Top of joist ," the " Bay pitch " is a positive number.

Panel layout: Automatic or Panel width or Number of panels or Panel point spacing . This " User preconfigured panel " option applies when the " Panel display method " is ' User pre-config '. It can also apply when the " Panel display method " is ' Automatic ' and ' User pre-config ' has been selected as the " Panel display method " at Home > Project Settings > Job > Joist Manufacturers .

' Automatic ' attempts to use the depth of the " Section size " as the panel width.

' Panel width ' lets you enter the panel width, which results in the " Number of panels " and " Panel spacing " being automatically calculated to fill the available space.

' Number of panels ' lets you enter the number of panels, which results in the " Width " and " Panel spacing " being automatically calculated to fill the available space.

' Panel point spacing ' lets you enter the spacing between panel points, which results in the " Number of panels " and " Panel width " being automatically calculated to fill the available space.

Panel member material: Automatic or Angle or Channel or Round bar . This " User preconfigured panel " option applies when the " Panel display method " is ' User pre-config '. Regardless of the choice made here, the panel material is dummy material .

' Automatic ' looks at the joist type (K, KCS, LH, DLH, etc.) as described in this joist's " Section size ." It then looks at the the User pre-configured panel table at Home > Project Settings > Job > Joist Manufacturers to determine what material to use for that joist type. The table sets the section size (or rod diameter) of that material.

' Angle ' sets the diagonals in the joist panel to be angle material. The " Configuration " can be set to ' Automatic ' or ' Crimped single angle ' or ' Double angle '. The " Panel section size " is, by default, the angle size specified in Joist Manufacturers , or you can specify an angle section size of your own choosing.

' Channel ' sets the diagonals in the joist panel to be channel material. The " Panel section size " is, by default, the smallest available channel section size (e.g., ' MC3x7.1 '), or you can specify a channel section size of your own choosing.

' Round bar ' sets the diagonals in the joist panel to be round bar material. The " Configuration " can be set to ' Auto filler thickness ' or ' User rod ' as described below.

Configuration : Available choices depend on whether the " Panel member material " is ' Angle ' or ' Round bar '.

' Automatic ' or ' Crimped single angle ' or ' Double angle ' apply when the " Panel member material " is ' Angle '.

' Automatic ' reads the configuration specified at Home > Project Settings > Job > Joist Manufacturers .

' Crimped single angle ' specifies that each panel member is a single angle whose " Panel section size " is as specified below. This is a configuration commonly used in joist manufacturing. The angle centroids are oriented to prevent eccentricities and provide uniform distribution of loads. The crimped portion of the angles fit between the top or bottom chord materials.

' Double angle ' specifies that each diagonal in the joist consist of a NS angle and FS angle, with each such angle welded to the NS or FS top and bottom chord materials. Each angle is the " Panel section size " that is specified below.

' Auto filler thickness ' or ' User rod ' apply when the " Panel member material " is ' Round bar '.

' Auto filler thickness ' lets the joist program determine the diameter of the round bar panel materials using the filler thickness assigned to the joist " Section size " in the local shape file.

' User rod ' lets you specify the " Panel section size " to be used for the round bar panel materials.

Panel section size : An angle section size or a round bar section size or a channel section size . Validation will not let you enter a section size that is not in the local shape file .

To enter an angle section size, the " Panel member material " must be ' Angle '. You can type in the angle section size , or you can press the "file cabinet" browse button ( ) and double-click any section that is on the list of available angle materials.

To enter a round bar section size, the " Panel member material " must be ' Round bar '. You can type in the round bar section size , or you can press the "file cabinet" browse button ( ) and double-click any section that is on the list of available round bar materials.

To enter a channel section size, the " Panel member material " must be ' Channel '. You can type in the channel section size , or you can press the "file cabinet" browse button ( ) and double-click any section that is on the list of available channel materials.

To get connection materials in the model so that you can assess the situation and make needed changes, check the box for " Force ." The Connection Design Calculations report (and Expanded Connection Design Calculations ) include a warning that the connection has been forced.

A special application: Suppose you get the end connection failure message " Flush framed joist connection only valid for Vulcraft joists " instead of a ' Flushed frame shear ' connection. Checking the box for " Force " will get you a connection without your having to set the" Joist manufacturer " to ' Vulcraft '.

' Graphical ' may have been set to " Graphical " automatically as a result of a user employing modeling operations to modify the system connection on this end of the member, thus making it graphical .

A graphical connection will not be changed by connection design . On this window, you will not be able to change any of that connection's " Connection design locks ." The Connection Design Calculations report (and Expanded Connection Design Calculations ) will include the warning " GRAPHICAL CONNECTION -- STRENGTH CALCULATIONS NOT GENERATED ." If " Graphical " is checked and you switch it to " Graphical " then press " OK " (so that Create Solids is performed), user-added modifications to that connection will be overwritten or erased. For example, user-added materials and holes will disappear. On the General Information window for each of the connection materials, you will see that switching from " Graphical " to " Graphical " caused the connection materials that were regenerated to be changed from " User modified connection material " to " System created connection material ."

See the topic " Determining left end & near side " if you are unsure which end of this joist is the left end and which is the right end.

Top of joist : Automatic or Elevation or Elevation @ extension end .

VIDEO The choices that can be made to " Top of joist ." (Recorded in SDS2 Detailing , v2017.)

' Automatic ' lets the joist program automatically adjust the elevation of the top chord to -- for the general case -- be the " Input elevation " plus the depth of the " Bearing shoe ." When ' Automatic ' is selected, the read-only value that is reported for " Elevation " is this automatically calculated elevation.

' Elevation ' lets you enter the left- or right-end top chord top elevation (a distance in the primary dimension " Units " or other units ). Changing this elevation moves the left- or right-end of the joist up or down. The top of joist elevation is in vertical alignment with the input point.

A joist in stick form with the " Joist outline " option in Display Options turned on (checked). The origin symbol ( ) of the joist is at the " Top of joist " elevation of the left end of the joist.

To determine the joist top chord elevation in the 3D model, use Construction Line Add or a similar tool, select EXPT as the Locate option, then snap the point location target to the top chord at either end of the joist. The Z coordinate reported in the X-Y-Z display tells you the elevation at the snapped-to exact point.

Note: The example above shows a joist-to-beam bearing connection. For a flush framed joist to a beam, the top-of-joist elevation that is entered here needs to match the top-of-steel elevation of the beam. If the top elevations don't match, connection design emits the failure message, Flush framed joist elevation not at supporting beam top of steel .

' Elevation @ extension end ' may be the choice that you want to select when the joist is sloping and its top chord has been extended. You can then enter the elevation at that extension end (a distance in the primary dimension " Units " or other units ).

VIDEO A sloping joist is added. For " Top chord ," a ' Chord only (S type) extension ' is added and the ' Elevation @ extension end ' is adjusted for " Top of joist ." (Recorded in SDS2 Detailing , v2017.)

Supporting chord : Top or Bottom . Changing the choice that is made here may move the relevant end of the joist up or down.

' Top ' specifies that it is the joist's top chord should connect to the supporting member at the " Input elevation " of the relevant end. In the industry, this is referred to as the "underslung end."

' Bottom ' specifies that it is the joist's bottom chord should connect to the supporting member at the " Input elevation " of the relevant end. In the industry, this is referred to as the "square end."

Bearing shoe: Automatic or Depth or Elevation .

VIDEO For a joist bearing on a beam's top flange, " Bearing shoe " elevation is the same as the joist member's " Input elevation ." For a joist to column with a seated connection, these two elevations can be different. (Recorded in SDS2 Detailing , v2017.)

For a joist bearing connection, the input elevation and shoe elevation are the same, and therefore the fields that report those elevations are marked as linked.( )

For a joist seat, the input elevation and the shoe elevation are different, and therefore the fields that report those elevations are marked as unlinked ( ). Also, the shoe depth is measured at the face of the supporting column.

' Automatic ' sets the bearing shoe depth to be the shoe depth that is specified in the local shape file for the " Section size " that is selected. When the " Input connection type " is ' Seated ', the joist program may adjust the shoe depth to prevent top chord infringement.

' Depth ' reports the ' Minimum bearing depth ' that is required. This requirement will match the shoe depth specified in the local shape file if the joist does not slope. However, if the joist slopes, you will need to set " Bearing shoe " to ' Depth ' and enter a depth that is greater than or equal to the minimum if you want a connection. See the end connection failure message " Joist shoe depth is less than required minimum ." A joist's minimum shoe depth is the " Shoe depth " that is entered in the local shape file for whatever " Section size " is currently entered on this window.

' Elevation ' is, for the general situation of a joist bolted to a beam's top flange, linked to the " Input elevation " This means that if you change that " Input elevation ," this shoe elevation will also change. When the two elevations are linked, a linked icon ( ) is shown. When the linked icon has been replaced with a not linked icon ( ), you can edit this setting (bearing shoe " Elevation ") and the " Input elevation " separately. The two elevations are different -- not linked -- when the joist end has a seated connection.

Input elevation : The left- or right-end bearing elevation (a distance in the primary dimension " Units " or other units ). Changing this elevation moves the left- or right-end of the joist up or down. This is the elevation that will be used for node matching, framing situation checking and connection design. Consequently, if this elevation is not correct, the connection might fail.

This example shows a joist in stick form with the " Joist outline " option in Display Options turned on (checked). The X that is the input point for this joist is at the " Input elevation " of the left end of the joist.

To determine the input elevation on a Joist in the 3D model, use Construction Line Add or a similar tool, select EXPT as the Locate option, then snap the point location target to the X that is shown at the end of the joist. The Z coordinate reported in the X-Y-Z display tells you the elevation at the snapped-to exact point.

Note: The input point is marked with an X at both the left and right end of a joist. That point is an exact point ( EXPT ). This applies regardless of whether the joist is displayed in stick form, or in one of the three solid forms .

Shoe length : Auto or Auto .

In this example, the " Shoe length " on the right end of the joist is set to " Auto ." The joist program calculates the required shoe length based on the joist field clearance and width of the seat on which the joist bears.

' Auto (checked) ' sets the shoe length, when possible, to be the shoe length that is specified in the local shape file for the " Section size " that is selected and reports that length as read-only ( grayed out ). The joist program may calculate a shorter shoe length if the joist bolts to a narrow flange or a narrow seat.

' Auto (not checked) ' lets you enter a shoe length in the primary dimension " Units " or other units .

Shoe pitch ( in/ft or mm/250mm ) : Auto or Auto . If the current Fabricator Setup " Units " are ' Imperial ', the " Shoe pitch " is reported in in/ft . For ' Metric ' units, the " Shoe pitch " is reported in mm/250 mm . Pitch can be positive (+) or negative (-).

In this example, the " Shoe pitch " and " Bay pitch " have the same magnitude, but opposite signs.

' Auto (checked) ' automatically calculates the shoe pitch so that the shoe is flat to the supporting beam or seat. The calculated auto length is reported as read-only ( grayed out ).

' Auto (not checked) ' lets you enter a positive or negative (-) pitch in in/ft (imperial) or mm/250 mm (metric).

Top chord pitch ( in/ft or mm/250mm ) : Auto or Auto . This " Profile " option applies when the joist " Shape " is ' Double pitch ' or ' Scissor ' or ' Triple pitch '. If the current Fabricator Setup " Units " are ' Imperial ', the " Top chord pitch " is reported in in/ft . For ' Metric ' units, the " Top chord pitch " it is reported in mm/250 mm . Pitch can be positive (+) or negative (-).

On a triple pitch joist, a different " Top chord pitch " can be entered for the left end and the right end. When different pitches are entered, the center section of the joist is sloped.

' Auto (checked )' instructs the joist program to automatically calculate the top chord pitch.

' Auto (not checked) ' lets you enter a pitch in in/ft (imperial) or mm/250 mm (metric). For a ' Double pitch ' or ' Scissor ' or ' Single pitch ', the value you enter as the " Top chord pitch " for the left end automatically causes the " Top chord pitch " for the right end to be recalculated. If the " Peak offset " is set to " Auto " for a ' Double pitch ' or ' Scissor ' (causing the peak to be centered), then the left- and right-end " Top chord pitch " are the same.

Bottom chord pitch ( in/ft or mm/250mm ) : Auto or Auto .

' Auto (checked) ' instructs the joist program to automatically calculate the bottom chord pitch. By default, when both the left- and right-end " Bottom chord pitch " are set to " Auto " and " Peak offset " is set to " Auto ," the bottom chord pitches will exactly match the left-end " Top chord pitch ."

' Auto (not checked) ' lets you enter a left-end " Bottom chord pitch " in in/ft (' Imperial ') or mm/250 mm (' Metric '). The right-end " Bottom chord pitch " is automatically calculated.

Triple pitch peak offset : Auto or Auto . This " Profile " option applies when the joist " Shape " is ' Triple pitch '.

' Auto (checked) ' instructs the joist program to automatically calculate the triple pitch peak offset. Allowing both the left- and right-end " Triple pitch offset " to be auto calculated creates a symmetrical joist that is divided into three sections approximately equal in length, with the middle section sloping parallel to the member line of the joist.

' Auto (checked) ' lets you enter a triple pitch peak offset in the primary dimension " Units " or other units . As long as you keep the left- and right-end " Triple pitch offset " the same, the center section of the joist is parallel with the member line of the joist.

Input connection type: Auto standard or User defined or Plain end or Bearing or Seated or Flush framed shear or Flush framed clip angle .

VIDEO When " Input connection type " is set to ' Auto standard ', a column cap plate is generated for the joist shoe to bear on and bolt to. Changing the " Input connection type " on the column changes the framing situation for the joist, and the new auto standard connection that connection design creates is a seated connection instead of the bolted bearing connection. (Recorded in SDS2 Detailing , v2017.)

VIDEO A joist is added to the top of a concrete wall, and ' Bearing ' is entered as the " Input connection type ." The entry that is made as the top chord " Schedule entry " is the bearing plate. (Recorded in SDS2 Detailing , v2017.)

YouTube video: Flush Framed Joists.

' Auto standard ' designs the connection on this end of the joist based on the joist's framing situation . Auto standard connections have a number of advantages .

If ' User defined ' is selected, the user defined connection file name must be entered to " User defined connection ."

' Plain end ' results in a system connection not being designed on this end of the joist. In pre-v2018 SDS2 software, ' Plain end ' could be selected to create a bearing connection. Now ' Bearing ' needs to be selected if you want connection design to attempt to create a bearing connection.

' Bearing ' can apply to a joist bearing on a beam flange or column cap plate. For a joist bearing on steel, the connection can be ' Bolted ' or ' Welded ' per " Chord-to-support " in " Connection specifications. " " Bearing " can also apply to a joist framing to a concrete wall. For a joist to concrete, a pocket for the joist top chord is created in the concrete. A " Joist End Pocket " leaf contains locks that control the construction of the joist pocket. Making a " Schedule entry " adds an embed to support the joist top chord.

' Seated ' is the selection to make in order to get a top chord seated connection to a column web or flange. ' Plate ' or ' Unstiffened L ' or ' Stiffened L ' or ' Tee ' may then be selected as the " Top chord seated ."

' Flush framed shear ' can apply to a joist that is framed flush to a beam or column. The joist " Section size " should typically be a CJ series, though connection design can create a flush framed shear connection for other series. To get a flush framed shear connection without resorting to " Force ," set Home > Project Settings > Job > Modeling > Joist Manufacturers > " Joist manufacturer " to ' Vulcraft '.

' Flush framed clip angle ' ( new ) can apply to a joist that is framed flush to a beam or column. You need to set " Joist manufacturer " to ' Vulcraft ' to get a connection without forcing it. The CJ series joist " Section size " is designed specifically for flush framed connections, but connection design can also create flush framed clip angle connections for other joist series.

Chord to support: Bolted or Welded . This " Connection specifications " option applies to a joist's top chord or bottom chord bearing on a beam's top flange when ' Bearing ' has been entered to " Input connection type ."

' Bolted '
' Welded '

' Bolted ' instructs connection design to add holes and bolts to the beam flange for bolting the joist to the flange. The holes are included on the beam's member detail. The bolts can be included on Field Bolt reports and, optionally, on the beam's bill of material. The " Input elevation " of the joist must be the elevation of the beam's top flange in order for holes to be generated. The distance between the two holes is the " Top chord gage " entered in the local shape file . The choice made to " Wide flange beams, alternative gage for joist connections " or " Channel beams, alternative gage for joist connections " in Home > Project Settings > Fabricator > Standard Fabricator Connections > Joist Connection Settings set the placement of the holes with respect to the center of the beam web. Hole size is set using the " NM bolt diameter " in the " Connection type " leaf on this window.

' Welded ' sets the joist to be field welded. A 3D field weld is not generated. The design calculations note, " Joist end welded to supporting member ."

' No ' instructs connection design not to add material plate washers on shoe slots.

Extend bottom chord: or . This " Connection specifications " option and the related options " Stabilizing material " and " Use erection hole " and " Vertical stabilizer angle " are available when the joist end's " Input connection type " is ' Seated ' or ' Bearing ' or ' Flush framed shear '. " Extend bottom chord " and its related options are also available at Home > Project Settings > Job > Connections > Auto Standard Connections and User Defined Connections .

If this box is checked ( ), the bottom chord of the joist is extended and " Bottom chord " is set to " Auto" so that the appropriate field clearance is applied. " Stabilizing material " is optional.

If the box is not checked ( ), you can still apply a " Bottom chord " setback to get a bottom chord. However, " Stabilizing material " cannot be applied.

Stabilizing material: None or Angle or Plate . The plate/angle shop welds to the supporting member and field welds to the supported joist. 3D field weld is not generated. Only the shop weld to the column is shown in the model. Connection design changes the connection material from ' Angle ' to a ' Plate ' when the bottom chord extension connects to a pipe column.

' Angle '
' Plate '

' None ' results in no joist bottom chord stabilizing material being created by connection design.

' Angle ' instructs connection design to use the Home > Project Settings > Fabricator > Standard Fabricator Connections > " Bottom chord extension seat angle " as the angle seat for the extended bottom chord.

' Plate ' instructs connection design to use the Home > Project Settings > Fabricator > Standard Fabricator Connections > " Bottom chord extension plate " as the stabilizing material for the extended bottom chord. Per the OSHA standard, the plate includes a 13/16 inch (21 mm) hole (click here ) for guying or plumbing cables. The hole is placed 1 1/2 inch from the bottom edge and joist edge of the plate.

Use erection hole: Automatic or Yes or No . This " Connection specifications " option applies when, for this end, " Extend bottom chord " is checked and the " Stabilizing material " is ' Plate '.

" Use erection hole " sets whether or not a bottom chord stabilizer plate has an erection hole.

' Automatic ' instructs connection design to use the entry (' Yes ' or ' No ') that is made to the relevant cell at Home > Project Settings > Fabricator > Standard Fabricator Connections > Joist Connection Settings > " Use erection hole " on the " Joist type specific settings " table. That setup table can configure an erection hole to be used or not used on a per-joist-type basis.

' Yes ' instructs connection design to add a hole for guying or plumbing cables to the bottom chord stabilizer plate. Per OSHA, the hole is placed 1 1/2 inch from the bottom edge and joist edge of the plate. A connection design lock for specifying the " Erection hole diameter " is made available in the " Joist Stabilizer Plate " leaf.

' No ' instructs connection design to not add an erection hole.

Vertical stabilizer angle: or . This " Connection specifications " option applies when, for this end, " Extend bottom chord " is checked and ' Angle ' is selected as the " Stabilizing material ."

Regardless of the choice made here, the stabilizer angle shop welds to the supporting member.

If this box is checked ( ), the bottom chord stabilizer angle is oriented with both legs vertical. That angle is vertically centered with respect to the bottom of the joist bottom chord.

If the box is not checked ( ), the stabilizer angle is oriented so that one leg is horizontal so that it can support the joist bottom chord.

Top chord : ' Auto or Chord only (S type) extension or Full (R type) extension or Field clearance or Setback . All of these dimensions require that you enter a positive distance from the input point. All except ' Field clearance ' are horizontal dimensions. ' Field clearance ' is measured parallel with the slope of the joist.

VIDEO A sloping joist is added. For " Top chord ," a ' Chord only (S type) extension ' is added and the " Elevation @ extension end " is adjusted for " Top of joist ." (Recorded in SDS2 Detailing , v2017.)

' Auto ' instructs the program to automatically apply a field clearance when the " Auto " field clearance for non auto standard connections is the " Joist to beam " or " Seats " field clearance that is entered at Home > Project Settings > Job > Field Clearances . Turning auto off (" Auto" ) lets you enter a different field clearance or change " Top chord " to ' Chord only (S type) extension ' or etc.

' Chord only (S type) extension ' can be selected for " Top chord " when " Auto " is off (not checked). It is the horizontal distance (in the primary dimension " Units " or other units ) from the input point ( X ) of the joist to the end of the extension.

Even if the joist slopes, this dimension is measured horizontally. A " Shoe " extension can optionally be applied to a ' Chord only (S type) extension '.

' Full (R type) extension ' can be selected for " Top chord " when " Auto " is off (not checked). It is the horizontal distance (in the primary dimension " Units " or other units ) from the input point ( X ) of the joist to the end of the extension. Unlike a chord only extension, this extends the shoe along with the top chord.

Even if the joist slopes, this dimension is measured horizontally.

' Field clearance ' may be entered by a user when " Auto " is off (unchecked).

For a joist to beam ' Bearing ' connection, the field clearance is the distance parallel with the member line of the joist (in the primary dimension " Units " or other units ) from the input point of the joist ( X ) to the top of the joist's top chord. This distance is measured along the top of the joist's top chord.

For a joist seat, the field clearance is the distance parallel with the member line of the joist (in the primary dimension " Units " or other units ) from the top edge of the joist's top chord to the face of the supporting member.

' Setback ' can be selected for " Top chord " when " Auto " is off (not checked).

The setback is the horizontal distance (in the primary dimension " Units " or other units ) from the input point to the edge of the joist. For a seated connection, the field clearance and setback are different dimensions.

For a horizontal joist bearing on a web vertical beam's top flange, the setback is equal to the field clearance.

Flush framed connection fail message: User top chord setback less than minimum required

Shoe : ' Auto or Extension or Field clearance or Setback . These dimensions position the top chord left- or right-end shoe. They require that you enter a positive distance from the input point. ' Extension ' and ' Setback ' are horizontal dimensions. ' Field clearance ' is measured parallel with the slope of the joist.

' Auto ' instructs the program to automatically apply a field clearance. Turning auto off (" Auto" ) lets you enter a different field clearance or an " Extension" distance or etc.

' Extension ' can be selected for " Shoe " when "' Auto" is off (not checked) and a choice other than ' Full (R type) extension ' is selected for " Top chord '. Entering an extension that is too large can result in the failure message " Joist shoe extends beyond top chord ." " Auto " results in this joist having the " Shoe length " that is specified in the local shape file.

Even if the joist slopes, this dimension is measured horizontally. A " Shoe " extension can optionally be applied to a ' Chord only (S type) extension '.

' Field clearance ' may be entered by a user when " Auto " is off (unchecked).

For a joist to beam ' Bearing ' connection, the shoe field clearance is the distance parallel with the member line of the joist (in the primary dimension " Units " or other units ) from the input point of the joist ( X ) to the edge of the shoe.

For a joist seat (not shown), the shoe field clearance is the distance parallel with the member line of the joist (in the primary dimension " Units " or other units ) from the edge of the shoe to the face of the supporting member.

' Setback ' can be selected for " Shoe " when " Auto " is off (not checked).

Bottom chord : ' Auto or Extension or Field clearance or Setback . All of these dimensions require that you enter a positive distance from the input point. ' Extension ' and ' Setback ' are horizontal dimensions. ' Field clearance ' is measured parallel with the slope of the joist.

VIDEO On the right end of a joist, a ' Full (R type) extension ' is selected for the " Top chord " on the right end and an extension of 2-0 ft is entered. A smaller extension is applied to the left-end top chord. To the right-end bottom chord, a ' Setback ' of 3 inches is entered. Then the previously changed settings are reset back to " Auto ." to make the extensions go away. (Recorded in SDS2 Detailing , v2017.)

' Auto ' instructs the program to automatically apply a field clearance when " Extend bottom chord " is checked. When " Extend bottom chord " is turned off, an auto setback is applied. Turning auto off (" Auto ") lets you enter a different field clearance or an " Extension " distance or a ' Setback '.

An ' Extension ' distance may be entered by a user when " Auto " is off (unchecked). It works much the same as when ' Full (R type) extension ' is selected for the " Top chord ," but applies to the bottom chord.

A ' Field clearance ' distance may be entered by a user when " Auto" is off (unchecked). It works much the same was as when ' Field clearance ' is selected for the " Top chord ," but applies to the bottom chord.

A ' Setback ' distance may be entered by a user when " Auto" is off (unchecked). This works just like selecting ' Setback ' for the " Top chord ," except that this applies to the bottom chord.

  • A left- and right-end " Summary " leaf can be shown on this window only if you are editing one joist. There is no summary if you are editing multiple joists.
  • The leaf gives you a summary of connection information related to the left or right end of the joist.

  • The summary shows (in parentheses) the " System designed connection " on that end of the joist.
  • If other joists have been assigned the same piecemark as this joist, the summary will list those other joists by member number . These are the joists that will be changed if, after you close this window, you press the " Yes " button when prompted to change all .
  • " Connection design locks " on this window that were locked ( ) because the " Input connection type " is ' User defined ' are reported as " Locked Via User Defined ." All other locks on this window that are locked ( ) are reported as " Locked Via Member Edit ."

  • Locked ( ) connection design locks are entries made by users.
  • Unlocked ( ) connection design locks are values entered by connection design . Many of the unlocked fields are populated based on user-entered setup choices.
  • Changing a locked ( ) setting or locking/unlocking a field triggers connection design to recreate the connection and update the limit state information. The limit state information tells you the capacity of the designed connection.
  • These same connection design locks may also be found (and revised) on the Connection Component Edit window for this connection.
  • When checked, " Show images " displays drawings for connection design locks.

    Right end limit state

The limit states for a seated plate connection on the left end of a joist. In this example, the connection passes.

VIDEO Limit states are placed below the navigation tree when the left-end or right-end settings are collapsed. (Recorded in SDS2 Detailing , v2015.)
  • A limit state is a potential connection failure mode. Each " Value " reported in the example above represents the strength of the connection or of the joist itself or of its supporting member with respect to a particular limit state.
  • The capacity of a connection is calculated for various limit states during connection design , and the left-end and/or right-end limit states tables on this window will be updated any time that connection design takes place.
  • Node matching , connection design and framing situation checking takes place within this window, whenever you change a " Connection specification " or a load or a connection design lock or any other connection-related setting. This is referred to as process on the fly.
  • If connection design determines that the capacity of an end connection is insufficient to stand up to the " Loads " on a member end, it fails the connection and generates an end connection failure message.
  • When you make changes to connection design locks , referring to the reported limit states can help you to better assess how your changes affect the capacity of the connection.
  • The Design Calculations Report together with the Connection Calculation Cover Sheet (or the Expanded Connection Design Calculations as a stand-alone report) provide formulas and the results of calculations (or the actual calculations) that relate limit states to the design of the specific connection.

"Copy" "Paste" "Save" "Load" apply to all fields on this window. They do the same thing as the "Copy" "Paste" "Save" "Load" buttons ( ) found above individual leaves on this window -- except that they apply to the entire window instead of individual leaves or sections.

"Properties" opens the Edit Properties window, on which you can make entries to custom properties . If, at the time it was created, your current Job was set to use a legacy flavor, the window that opens is named Custom Properties , not Edit Properties .

The Edit Properties window can also be used to read " Log " entries or review or type " Notes ."

Tip: Model > Member > Properties is an alternative to this button. It opens the Edit Properties window directly, without your first having to open a member edit window.

" Status " opens the Status Review window, which can give you additional information about this joist, and which you can use to enter status information.

Note: This button is orange if one or more " Repeat " check boxes on the Member Status Review window do not match the checked-unchecked state of same-named fields in User and Site Options > Site > " Items to Copy/Repeat ." On the Status Review window, the fields that do not match User and Site Options are printed in red .

" OK " (or the Enter key) closes the Joist Edit window and saves any changes made on the window to the member file of the affected joist.

Solids on "OK": If the appropriate choice is made to User and Site Options > Modeling > " Automatically process after modeling operation ," then this joist's end connections will automatically be regenerated ( Create Solids will take place) after your press " OK ." Otherwise, you can manually Process and Create Solids in order for changes you made on this window to be fully updated in the 3D model.

Change all: If you Edit Member (one joist only) and make a change that potentially triggers the " Do you want to change all ... " dialog and the 3D model contains more than one joist that has the same piecemark as the joist you changed, a yes-no dialog opens. On it is the question, " Do you want to change all (members with this piecemark). " Press the " Yes " button to change all the members; press the " No " button to change only this joist. Special cases are listed on the table below:

  Do not trigger change all ...   Not changed with change all ...
 " Sequence "  " Sequence "
 " Piecemark "  " Load " settings
 " Member category "  " Model complete date "
 " Member description " Example: " Yes " or " No " on the dialog changes the " Sequence " of this member (1 joist) only.
 " Member routes "
 " Model complete date "

Defaults for to-be-added joists: If you are adding a joist and press " OK ," the settings on this window become the default settings for the next joist you Add in this session of Modeling . Even if all you do is double-click a joist and press " OK " without making any changes on this window, this window's settings become the defaults for the next-added joist. On the other hand, the settings on this window do not become the defaults for new joists if you are editing multiple piecemarks or if you press " Cancel " to close this window.

" Cancel " (or the Esc key or the button) closes this window without saving any changes.

Note: If you opened this window using Add Joist , pressing " Cancel ," brings you back to the work point location step of adding a joist.

Tip: Any time you Edit Member just to review a member (and you do not want to set the defaults for to-be-added members), the best way to close this window is to press " Cancel. "

" Reset " undoes all changes made since you first opened this window.

"Design Calc" outputs the Design Calculations report (also referred to as Short Calcs) which includes design calculations, general settings, and left/right end settings. A report for each joist you are editing is output to a destination of your choice as a PDF file. The file automatically opens with your operating system's default PDF application when you are editing one joist at a time.

"Expanded Calc" outputs the Expanded Connection Design Calculations . First a PDF of the report is output to a destination of your choice. For example, to your desktop. Then the report is automatically shown in your help browser so that you can review it without manually opening the PDF file.

Expanded Connection Design Calculations give you the calculation results found in the Connection Design Calculations , plus show you the calculations written out, in detail, in the report itself, instead of simply reporting the results.

If you are editing multiple joists with the same piecemark (or different piecemarks), you get a report for each brace.

Connection design failures can be found with the aid of a search or by a quick scan of the document. Calculations that result in a connection failure are identified as " (NO GOOD) " in their concluding line. You might also search for the string "CONNECTION DESIGN FAILURE".
