Combined shear and patch loading of girders with corrugated webs

Abstract

The corrugated steel plate has been increasingly used as web of steel and composite bridges. When such a bridge is incrementally launched, the web panels are often subjected to combined shear and patch loading. There are only a few investigations available in the literature which are dealing with this interaction type, therefore the current research of the authors focuses on the analysis of the combined shear and patch loading in case of corrugated web girders. Based on patch loading tests executed on 12 short span specimens, a numerical model is developed and verified. A numerical parametric study is conducted to analyse the structural behaviour and the interaction between shear and patch loading in the typical parameter ranges used in bridges. Based on the large number of numerical calculations a design equation for interaction of shear and patch loading is proposed.
