Intermediate Diaphragm Loads

I am using a Project Library Entry that I created for a specific girder with intermediate diaphragms located at 0.25 points. The diaphragm weight is input directly in the Project Library Entry. When reviewing Loading Details in the Details Report, the load reported under Intermediate Diaphragm Loads Constructed at Bridge Site for the far quarter point is larger than the load reported for the near quarter point which appears incorrect.

My PGSuper file is attached.

Thank you for bringing this

Thank you for bringing this issue to our attention. It has uncovered a subtle bug in the way the intermediate diaphragm loads are applied when defined as Weight/Length.
You can work around this issue. You can define intermediate diaphragms based on a height and thickness and letting PGSuper compute the loading. Alternatively, you can remove the intermediate diaprhagm rule and apply the weight of the diaphragm as user defined concentrated loads.
I'll get this issue resolved for the next release.
Best regards,
Rick
