Piecemark or System piecemark or User piecemark or Frozen piecemark :
Sequence :
Shape: Parallel or Single pitch or Double pitch or Arched chord or Bowstring or Scissor or Triple pitch or BIM custom .
|
|
' 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 a joist manufacturer. 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.
|
|
The " Peak offset " option applies 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 applies 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 the joist is rotated. As shown in this example, the left-end top chord reference symbol ( ) stays vertically alligned 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 made here does not affect the types of connections that can be generated for a joist. It only affects the appearance of the joist, not its functionality.
' Automatic ' applies the choice made to " Panel display method " in Joist Manufacturers ( Home > Project Settings > Job ).
' 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, the joist is displayed as if ' Reserved ' had been selected.
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 are applied to the joist.

Panel member material: Automatic or Angle or Channel or Round bar. This " User preconfigured pane " option applies when the joist's " Panel display method " is ' User pre-config'.
' Automatic ' looks at the joist type (K, KCS, LH, DLH, etc.) as described in this joist's " Section size ." It then looks to Joist Manufacturers ( Home > Project Settings > Job ) to determine what material to use for that joist type.
' 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 '.
'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).
' 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 '.
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 specifed in Joist Manufacturers ( Home > Project Settings > Job ).
' 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 ' indicates that the user of a full-featured SDS2 program .has specified 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 .

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

Load (kips or kN): The load on this end of the joist in kips (kilonewtons for ' Metric '). The loads for each end of a joist must be entered for a full-featured SDS2 program to do the proper calculations.
Note: AISC requires a minimum of 6 kips for all connections (10 kips for LRFD )."

A left- and right-end " Summary " can be shown on this window only if you are editing one joist. There is no summary if you are editing multiple joists.
The "
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 .

The limit states for a seated plate connection on the left end of a joist. In this example, the connection passes. |
A limit state is a potential connection failure mode.
The capacity of a connection is calculated for various limit states during connection design . 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.
Since connection design takes place in a full-featured SDS2 program , but not in SDS2 Site Planning, the limit states that are reported on this review-only window are static and cannot be changed.
If connection design in a full-featured program has determined that the capacity of a connection is insufficient to stand up to the "
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.

"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 "
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 review window.
" Status " opens the Member Status Review window for the joist(s) that you are reviewing. You can use that window to update status information about the joist(s).
" OK " (or the Enter key) closes the Joist Review window (this window) and saves to the member file(s) any changes made on the Member Status Review window.
Change all: If you double-clicked a joist and made a change to its status and the 3D model contains other joists with the same piecemark as this joist, a yes-no dialog opens after you press " OK ." On that yes-no dialog is the question, " Do you want to change all .... " Press the " Yes " button to update the status of all the joists with this piecemark; press the " No " button to change only this one joist.
Tip: The yes-no "change all" dialog tells you the count of the members with this " Piecemark ." Another way to find out the count of members under the piecemark is to look under the "
" Cancel " (or the Esc key) closes this window without saving any status changes made on the Member Status Review window.
" Reset " undoes all status changes you made to this member on the Member Status Review window.
"Design Calc" outputs a report that includes this joist's connection design calculations, general settings and left/right end settings. If you are reviewing multiple joists with the same piecemark (or different piecemarks), you get a report for each joist. Each report is output to the destination specified at User and Site Options > Output > " Reports ."
Tip: To get a report listing similar specifications for multiple members, output a Check Report and a Design Calculations Report .
"Expanded Calc" outputs the Expanded Connection Design Calculations . Output is to your web browser.
Expanded Connection Design Calculations is a report that provides all of the information in the Connection Design Calculations combined with related information from the Connection Calculation Cover Sheet . In addition, the report shows you the calculations written out, in detail, in the report itself, instead of simply reporting the results. Certain browser requirements must be met in order for you to access this report.
If you are reviewing multiple joists with the same piecemark (or different piecemarks), you get a report for each joist.
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".
