Abstract

Abstract

The box girder with corrugated steel webs is a new type of composite steel concrete structure. Compared with conventional box girders with concrete webs, the influence of shear deformation may be not ignored in its deflection calculation. Combining structural properties of box girder with corrugated steel webs and the theory of elementary beams, a calculation method of its deflection under flexure, which considers the influence of shear deformation on it, is provided. The results of model tests and finite element analysis further testify it. With different shear span ratios, the influence of shear deformation on the box girder deflection is different, thus a limit value of shear span ratio is suggested for considering the influence of shear deformation or not.
