Abstract
Due to its advantages corrugated steel plates are widely used in various applications. Engineers realized a potential application field in bridges, especially in composite bridges. When such a bridge is incrementally launched, the girder is subjected to combined action of bending moment, shear and transverse forces, resulting in a complex stress field and interacting instability phenomena. The current paper focuses on the experimental and numerical investigation of the structural behaviour of the girders with corrugated webs under all of the above mentioned actions. 12 large scale test specimens are investigated under combined patch load and bending moment. Based on the experimental investigations a numerical model is developed and the structural behaviour of the girders with corrugated web is analysed under the complex loading situation due to combined bending moment, shear force and patch loading.
