•Requirement of intermediate transverse stiffeners in HSS plate girders was investigated.•AASHTO design equations can not be directly used for transverse stiffeners in HSS plate girders.•Additional out-of-plane deflection leads to an adverse effect on shear resistance. The postbuckling capacity of H...
