Abstract Abstract： In this paper, a study on elastic shear buckling of corrugated web girders with circular openings was conducted. A finite element model was established and the elastic buckling load was obtained through eigenvalue buckling analysis. The influence of diameter of opening, web height, web thickness, the transverse and longitudinal eccentricity of opening on the elastic shear buckling was investigated. Based on lots of finite element numerical analysis, the calculation formula for elastic shear buckling capacity of corrugated web girders with circular opening was derived in the form of reduction coefficient.
