Paper Title:
Finite Element Analysis on the Bottom Slab of Box Beam in Zhaohua Beijiang Bridge under Radial Force
  Abstract

Based on summarizing the purpose and main working conditions of horizontal analysis of the box beam in bridges, combined with the force status of the chambers under the radial force of the bottom slab in Zhaohua Beijiang Bridge, the stress distribution in the cross-section under the pre-stressed radial force of the bottom slab at the center of a span of 210m and 85m respectively is analyzed with finite element method. The horizontal and vertical stress distribution and chambers displacement under the radial force are respectively researched. The results show that appropriate size should be used in the angle between both sides and the end of a box beam with a large span; the box beam lower, the girder webs bending stress generated by the radial force greater; the bending stress of the webs weakens their own principal stress state. These conclusions have certain significances for the study of the box girder stress, deformation and crack control.
