Analysis of Stress Concentration of Typical Defects in Box Girder of Bridge Crane

LI Zhong-hua

Abstract

This paper set up the finite element model of the box girder of a bridge crane,analyzed the stress concentration factor of the cracks with different shape in the girder under the same condition by ANSYS software.The influence of different cracks on the girder was discussed.It provides detailed data for the stress concentration and strength analysis of the bridge crane.
