Abstract

Mechanical behavior of box girder with corrugated steel webs in completion status of bridge was studied. Based on the cable stayed bridge of box girder with corrugated steel webs on Zhenshui Road in Xinmi City, finite element method (FEM) was applied to calculate and analyze vertical displacement of box girder, shearing stress of corrugated steel webs, normal stress and vertical deflection of concrete plates, longitudinal strain of box girder in completion status of bridge. The results show that vertical shearing stress of corrugated steel webs is approximately uniformly distributed along the height of box girder. Vertical deformations of corrugated steel webs play the dominant role in the whole box girder. Longitudinal strain of corrugated steel webs is smaller than that of concrete plate. Structural design method based on traditional theory that corrugated steel webs bear all the shear force is conservative. Keywords: box girder with corrugated steel webs; cable stayed bridge; deflection; stress; strain
