Abstract
In order to study the variation of transverse load distribution of T-beam bridge with transverse damage under moving load. In this paper, nine kinds of working conditions are proposed for the possible failure modes and the different locations of the failure, and relevant finite element models are established. Through simulation, the lateral load distribution of middle beams under nine working conditions is obtained and compared with that under non-damage condition. The results show that the transverse load distribution capacity of T-beam bridge under moving load will be greatly affected after the transverse connection damage of the diaphragm beam occurs. When the location of transverse damage is different, the influence of T-beam bridge will be different.
