Using corrugated web girders in civil engineering praxis have several advantages. In the majority of cases these steel girders with corrugated web are being used in bridges but these girders are applicable for industrial structures as well. In these girders plate buckling modes can occur such as flange buckling and shear buckling. Corrugated web girders have greater shear capacity than conventional I-girders proved by previous investigations. In the literature small number of investigations focused on the bending-shear (M-V) interaction behavior, in the literature we can not, however, find investigations focusing on the M-V interaction of hybrid trapezoidal web girders. Previous international studies give proposal for M-V interaction for those of girders having homogeneous steel strength (same for the flanges and web). EN1993-1-5 „Annex D” gives a proposal for shear strength and flange buckling resistances. Besides it gives reduction factor for bending moment when accompanying shear force acts. Therefore, this paper focuses on the M-V interaction behavior of hybrid trapezoidally web girder (different flanges and web steel quality) and focuses on the appropriateness of international shear buckling formulas. In the first part of the paper the previous proposals from literature are collected. In the second part a numerical model development and validation are carried out based on experimental test results from literature considering flange buckling and shear buckling type failure modes as well. Then in the third part of the research FEM-based M-V interaction resistance is investigated for both homogeneous (pure) and inhomogeneous (hybrid) steel corrugated web girders, and a design proposal is developed.
