virtis-superstructure definition at where skew angle changes

[johny13]

i have a simple support steel bridge that has different skew angle along the support. there is no long. joint where the skew angle changes. my question is, should we create new superstructure definition at location where skew angle changes? also there is a diaphragm connecting two stringers. refer attach file...

I would use a girder-line analysis and model each beam individually in this case.

I'm not sure how you could model that bridge as two separate superstructures since the superstructure is not discontinuous at the change in skew angles.
