With the high out-of-plane stiffness and shear buckling strength, the number of stiffeners and the thickness of the web can be reduced when using corrugated webs in composite girders. The finite element model is established according to the existing experimental results. The flexural behaviour of I-shape steel composite girders with the corrugated web was investigated by numerical analysis. From the numerical results, the flexural behaviour of I-shape steel composite girders can be improved by increasing the strength of materials. The concrete slab grade range of C50 to C60 was recommended to ensure full use of concrete and high strength steel material properties. The high strength steel grade with nominal yielding strength between 420MPa and 460MPa were suggested for bottom flange with priority, while steel grade no less than Q345 was suggested for corrugated web to avoid the safety risks caused by the premature reaching of the yield strength of the web. |
