Is there any way to place cross-frames and diaphragms between steel tub girders? The bridge that I am modeling has steel tub girder unit in several spans. I am trying to place cross-frames between them but do not get that option.
Currently it is not possible to assign Cross frames (Internal or External) for Tub Girders as it is a limitation in the program.
The workaround solution is to transfer the model to LBS and then assign the CF's for the Tub Griders.
I would suggest you give suggestion to the product development team to add this feature in the future version of OBM.
