This study investigates web shear buckling behavior of composite box girder according to the aspect ratio. The nonlinear finite element analyses on composite box girder model having shell elements and solid elements were performed. Also, the steel was modeled as an elasto-plastic material. Ultimate web shear buckling behavior of composite box girder was analyzed, and were compared the inelastic analysis results with shear buckling behavior of plate.
