Skew Angle: Define the skew angle for the diaphragm.
Is it an Intermediate or Pier/End Diaphragm? [Intermediate/Pier-End]: This parameter can be used to define whether the diaphragm is an intermediate diaphragm or a pier-end diaphragm.
Station [Start/ End]: If the diaphragm is defined as an intermediate diaphragm, a the station relative to the PGL can be specified by using this parameter to further define the diaphragm's location of the diaphragm. If the diaphragm is defined as a . This parameter is not applicable for pier-end diaphragm, this parameter will not be applicablediaphragms.
Select Pier/End: If the diaphragm is defined as a pier-end diaphragm, this parameter can be used to define the location of the diaphragm, as the support line can be selected. If the diaphragm is defined as intermediate, this parameter will not be applicable.
...
Material: Assign a material to the diaphragm. A material can either be imported or assigned from a previously defined one under Properties - Materials.
Section Details
Is Does the Top Flange Exist? [YES/NO]: Specify whether a top flange exists or not.
Is Does the Bottom Flange Exist? [YES/NO]: Specify whether a bottom flange exists or not.
...
Splice Gap at Bottom Flange: The figure has a splice gap at the bottom flange defined with a value of 0, while for the top flange, it is different from zero. See the figure below for visual representation.
Web Depth Computation [Use Girders Working Point/User Input]: The diaphragm web depth can be calculated based on two methods, specified by the definition of this parameter. The web depth can either be generated based on the girder geometry or manually defined by the user through the Web Depth and Diaphragm Vertical Offset from Top of Girder Web parameters.
Web Depth: If the Web Depth Computation parameter is set to ‘User Input,’ the Web Depth can be manually defined by the user using this parameter. Otherwise, if Web Depth Computation is set to ‘Use Girders Working Point,’ this parameter will be N/A.
Diaphragm Vertical Offset from Top of Girder Web: If the Web Depth Computation parameter is set to ‘User Input,’ the diaphragm's vertical offset from the top of the girder web (along the Z-axis) can be manually defined by the user using this parameter. Otherwise, if Web Depth Computation is set to ‘Use Girders Working Point,’ this parameter will be N/A.

Cope (Bottom Corners): For visual representation, refer to the figure below.
Is Does a Manhole Exist? [YES/NO]: This parameter can be used to specify whether or not a manhole exists on the diaphragm.
...
Axial Rigidity Coefficient: This parameter can be used to define the axial rigidity of the bracingdiaphragm.
