- If you are editing one beam, its member number (" Member xx ") is shown in the title bar. The "
Summary " lists other beams that have been assigned the same piecemark.
- If you are editing multiple beams , Beam Edit - Multiple Members is this window's title. This window is mostly read-only (titled Beam Review ) if the " Model complete date " is set and ' Restrictive ' is selected for any beam that is being edited.
- " 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 the [ Left end settings ] section apply to multiple leaves in that section. Click here for more information.

Shear thru plates can be designed with an axial load. Form buttons are used to " Copy " settings from the right end of one Beam Edit window and " Paste " them to the left end of the Beam Edit window on the opposite end of the shear thru plate connection. (Recorded in SDS2 Detailing , v2015.)
- " 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 cases: Form buttons do not operate on" Piecemark ", "End elevation ", and"ABM Options ." Tip: Right-click a " Load " button to get a list of recently created forms that can be applied to the section which that " Load " button governs. Selecting the name of a form from the list populates the fields in that section with the form settings that were saved under that name. - " Save " (
) places a file (which you name) in a subfolder of the 
form/beam folder in the data directory 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.

Section size: The beam's main material (e.g., ' W12x45 ' ). Only materials listed in the local shape file can be specified here.
| Valid Material Types for Beam Connections " Input connection type " connections can be generated when the beam's " Section size " is one of the following shapes: |
|
|
|
| wide flange ,
channel , welded plate W , S shape |
Connection design can create the full range of " Input connection types " and can automatically connect braces, beams and columns to a beam whose " Section size " is any of these types. " Moment " options must be applied to a flanged shape such as wide flange, welded plate wide flange or S shape.

HSS/TS (tube) |
Connection design can create clip angles (perp to W or tube beam/column), shear connections ( to tube or channel beams or perp to W or tube column) and end plates (perp to W or tube beam/column). Seats for tube beams are designed, even though field bolting a seat to a tube section can be problematic. Braces, beams and columns can automatically connect to tube beams.Connection design can create bent plates ( to W or S column) , but only with a paddle plates . |
| welded plate box |
If this beam end's " Input connection type " is ' Plain end ', connection design automatically sets back the beam and generates appropriate " End preparations " to prevent material interferences with the supporting member. Connections to a welded plate box beam can be designed on braces, columns and other beams.

Slab width: A distance (in the primary dimension " Units " or other units ) measured parallel with the beam's Z axis that represents the width of the concrete slab that is supported by the beam. For many cases, this is simply the beam spacing.
What distance to enter: For a beam that is not an edge beam, enter the distance between the center lines the adjacent beams and divide by two. For an edge beam, enter the smaller of either the distance from the edge of the slab plus half the distance to the adjacent beam, or the distance to the adjacent beam.
Note: If the beam span/4 is smaller than the beam spacing, enter beam span/4 as the " Slab width ." See the ASD 9th Edition Chapter I, Section I1, p 5-56 or the AISC Steel Construction Manual, Thirteenth Edition Section I3.1, p 16.1-83.

Beam rotation: The positive or negative number of degrees of rotation ( 180 to -180 ) from web vertical. If you are looking along the beam member line toward the left end of the beam, a positive entry rotates the beam counterclockwise around its workline that number of degrees.
|

' 0 ' (zero) degrees sets the web of the beam to be vertical. The selection made to the " Web rotation " field may override an entry of ' 0 ' made here if the box for " Hold rotations " is not checked and the beam frames between sloping beams.
A ' number between +/-180 degrees ' is applied only if the box for " Hold rotations " is checked. When the box for " Hold rotations " is not checked and a number other than ' 0 ' or ' 180 ' is reported here, then that number is the " Web rotation " for a ' Hip and valley ' or ' Web normal ' situation.
' 90 ' degrees rotates the web of the beam so that it is horizontal and makes the " Web rotation " not applicable. Connection design can only apply clip angles (to a column web or flange) on a beam that has been rotated 90 degrees. User base/cap plates can be added to a column framing to a beam with a horizontal web as described here . No matter what the beam end's " Input connection type ," connection design copes the member main material and sets it back to prevent material interferences with the member the beam frames to. You can " Center material " when ' 90 ' is entered.

Rolling operation: None or Camber annotation or Weak axis or Strong axis or Camber or Camber (Both) . The center of curvature for each of these choices (except ' None ' and ' Camber annotation ') is midway between the left and right end of the beam's main material. The work points of the beam are fixed, but the work line (stick form member line) becomes curved as a result of the rolling operation.

' None ' makes the main material straight, not curved.
' Camber annotation ' also makes the main material straight, not curved. Enter a " Mid-ordinate " (other than 0) to add a shop note when the beam is detailed . A negative (-) " Mid-ordinate " indicates the camber is down. A positive " Mid-ordinate " indicates up. The same " Mid-ordinate " value is added to the " Remarks " column in the member bill of material if " Show camber on the bill of material " is checked at Home > Project Settings > Fabricator > Detailing > Member Detailing Settings > " Beams " section. You can " Show camber on members " on erection view drawings or display " Camber annotations " in 3D Modeling erection views.
' Weak axis ' or ' Strong axis ' produce circular rolling. The " Mid-ordinate " or " Included Angle " or " Rolling radius " sets the offset at mid-span and the direction (+ or -) of that offset.
' Camber ' produces parabolic bending along the strong axis of the rolled section with the ends fixed. The " Mid-ordinate " sets the offset at mid-span and the direction (+ or -) of that offset.
' Camber (Both) ' combines ' Camber annotation ' with ' Camber '. The beam is shown as curved in the 3D model and on the member detail. You also get the camber annotation on the beam detail.

For both ' Weak axis ' and ' Strong axis ' rolling: The workline (stick form member line) and beam main material are adjusted to reflect the offset. The rolling remains circular.
For ' Weak axis ' rolling: A positive " Spiral offset " raises the elevation of the workline at its right-end point the exact distance that is entered. A negative " Spiral offset " lowers the elevation of the workline at its right-end point. For either sign (+ or -), the beam's right " End elevation " remains the same.
For ' Strong axis ' rolling: A positive " Spiral offset " offsets the workline at its right-end point the exact distance that is entered; the workline is offset in the direction of the near side of the beam. A negative " Spiral offset " offsets the workline in the direction of the far side of the beam.

' IMF ' and ' SMF ' seismic moment connections can be designed when the " Connection design method " is any LRFD edition. ' OMF ' seismic moment connections can be designed for LRFD and ASD editions.
' Automatic ' specifies that connection design apply a setup choice ( Home > Project Settings > Job > Design Settings > " Seismic moment frame type " > ' OMF ' or ' IMF ' or ' SMF ' ). For example, if that option in Design Settings is set to ' IMF ', then connection design will use IMF design for the seismic moment connection.
' OMF ' stands for "Ordinary Moment Frame." OMF connections are recommended for non-seismic or low seismic regions. When the " Connection design method " is ' LRFD 15 ' or ' ASD 15 ', only welded moment shear tab connections can be designed.
' IMF ' stands for "Intermediate Moment Frame." IMF connections are designed to be installed in moderate seismic regions.

- If different " Web rotations " are selected, the beam may be twisted.
- To move between the left and right " End elevation ," press the comma key [ , ] on your keyboard.
End elevation: The elevation (in the primary dimension " Units " or other units ) of the work point at this end of the beam. For a non-sloping beam, both the left and right end elevations are the same. The work points of a beam align with the top flange of the beam.
| A beam has two exact points , whose elevation you can change by changing the beam's left- and/or right-end " End elevation ." |
|
|
|
To determine the end elevation on a beam 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 work point at the end of the beam. The Z coordinate reported in the X-Y-Z display tells you the elevation at the snapped-to exact point.
Note 1: " Copy " " Paste " " Save " " Load " buttons do not operate on the " End elevation ."
Note 2: If you are editing one beam with a piecemark shared by at least one other beam and change its " End elevation " on one or both ends, you will get a notification dialog after you press " OK " to close this window. The dialog will remind you that you have the option to change the elevations of all beams with the same mark. If you choose to change the elevations of all beams with the same mark, the ends of the members will be moved in the same manner and by the same relative amount (not necessarily to the same elevation).
Note 3: If the beam setup option " Show end elevations on details " is on, then changing the " End elevation " causes the beam to be " Marked for detailing ."

Web rotation: Automatic or Web vertical or Hip and valley or Web normal . This " Member " option applies when the box for " Hold rotations " is not checked. When the box for " Hold rotations " is checked or " Beam rotation " is ' 90 ', the number of degrees entered to " Beam rotation " applies. Be sure to set this option correctly for both ends; otherwise the beam may become twisted. For a beam to a perfectly vertical column, select ' Web vertical '. For a beam that is perpendicular to a perfectly horizontal beam, selecting any of the four choices gives you the same results.
For a beam to a sloping column:
' Web vertical ' makes the web of the beam vertical to the world.
' Web normal ' rotates the beam so that its web aligns with the member line of the column.
For a skewed or nonskewed beam to a sloping beam:
' Automatic ' lets connection design choose the web rotation for you.
' Web vertical ' makes the web of the beam vertical to the world.
' Hip and valley ' rotates the web of the beam to keep its flange in the same plane as the flange of the sloping beam it is framing to.
' Web normal ' rotates the web of the beam as needed to keep the connection on the beam perpendicular to the flange of the sloping beam it is framing to.
Example: You frame a beam to a sloping beam to form a roof support. The other end of the beam has a plain end and frames to concrete. For the framing end, you select ' Web normal '. For the opposite end, you select ' Automatic ' in order to keep the beam from being twisted.

An " Embed schedule entry " needs to be made in order for you to get a bearing plate / angle / channel to a concrete wall or panel . Locks in the " Beam End Pocket " leaf control the pocket in the wall that the beam end sets on. A bearing embed is not a designed connection, but is a separate custom member. Settings for that member do not appear in a leaf on this window. Warning: If you select ' Bearing ' as the " Input connection type " for a beam end that does not frame to a concrete wall or panel, " Embed schedule entry " is disabled ( grayed out ) and you probably also get the end connection failure message " Member must frame into a concrete member ."

System designed connection: This " Connection type " field is a read-only . It tells you the type of connection that connection design created on this end of the beam (e.g., ' Clip angle ' or ' Bent plate ' or etc.). If a non-auto standard connection has failed , resulting in no solids model being created, the connection type that connection design attempted to design will still be reported here. The connection type reported here may be different than this beam end's " Input connection type " in the following situations:
If ' User defined ' or ' Auto standard ' is this beam end's " Input connection type ," the specific designed connection type is reported here. Press the " Design Calc " or " Expanded Calc " button for more information about that connection.
If an auto standard connection has failed , the connection type reported here is ' Plain end '.
If the specified " Input connection type " will not work, connection design may change the connection to something that will work. For example, if the ' End plate ' is specified as the " Input connection type " and the beam frames to a W8 column web, connection design will -- instead of failing the connection -- attempt to design a single-plate shear connection. A green banner notifies you that connection design has made such a change.

Shear load (kips or kN) : Auto or a user-entered load (in kips for ' Imperial ', kilonewtons for ' Metric '). The shear end reaction entered here -- under " Loads " -- will be combined with the " Shear load " entered to the " Gusset Interface Forces " column and then will used in the design of the " System designed connection " on this end of the beam. For beam splices, connection design attempts to synchronize the shear load on each of the two beams being spliced so that each load is the same value. If one beam has an " Auto " shear load and the other beam has a user-entered shear load, the load on both beam are set equal to the user-entered " Shear load ." If both beams have user-entered shear loads and those loads are not the same, the connection fails.

- 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 beam 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 when this window is opened and 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 a connection is insufficient to stand up to the " Loads " on a member, connection design fails the connection and generates a connection failure message such as:

"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 beam 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 beam at a time.
"Expanded Calc" outputs the Expanded Connection Design Calculations report. 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 beams with the same piecemark (or different piecemarks), you get a report for each beam.
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".
