Girders: Choose the two girders that are connected by the diaphragm x.
Skew Angle [deg]: A positive skew value rotates the diaphragm x in a clockwise direction, while a negative skew value rotates it in a counterclockwise direction. It is important to remember that the diaphragms are positioned at the specified station along a line perpendicular to the PGL, which is then rotated according to the entered skew value.

Station [ftStart/End]: Enter Define the station either using the options Start/End or by entering the station along the PGL.. When dealing with curved girder bridges, collecting distance along the girder length can lead to different inputs for the right and left girder that are connected by diaphragm, causing ambiguity. Therefore, collecting the station along the PGL is a more reliable solution to avoid such issues. Furthermore, since diaphragms are typically continuous in the transverse direction, entering the same station for all diaphragms ensures that their locations are consistent between each girder.
