Can cross members be prevented from buckling during buckling analysis for the Main edge girder of a highly skewed highway bridge? The solution should be apart from adding extra supports or bracing members, considering that the mode shapes show cross girders frequently buckle first, and jack arches exist but haven't been modeled.


There is no special function for this. How about increasing stiffness (Area, Iyy, Izz) of the cross girders using Section the Section Manager>Stiffness function?
