Abstract
In order to research the influence of web’s shear deformation on the deflection of composite girder bridge with corrugated steel webs in construction, the deflection calculation formulae considering shear deformation were deduced, which was to analyze the background engineering of Chuhe bridge deflection in different load conditions when it was in the maximum cantilever state. Finite element method analysis shows that the calculation formulae are credible and applicable, and also comparative study was done with practical measurement. Results show that the proportion of main deflection caused by shear deformation of web may reach 30% ~ 40%, and the deflection caused by shear deformation needs to be considered in the process of construction monitering.
