Abstract
This paper is a research on the effect of transverse connection damage on transverse load distribution of T beam bridge.The study consists of establishing the finite element models by the division of 9 working conditions according to the different positions and forms of damage;producing the transverse load distribution values of main beams under 9 working conditions,using a calculation and analysis method;and comparing the values with those damage-free ones.The results demonstrate that the transverse connection damage triggers the transverse load redistribution,with a resultant change in the transverse load distribution values of each main beams-a change which exhibits an increasing magnitude due to the damage degree;the transverse connection damage is followed by the occurrence of a significantly increased value culminating into a maximum value,in the transverse load distribution of main beams directly acted on by loads shows;the transverse connection damage is accompanied by both an increased values in the transverse load distribution of main beam subjected to load on the one side and a decreased value on the other side,as is shown by the damage point as the borderline.This research highlighting a rule underlying the change in transverse load distribution under transverse connection damages may provide a theoretical reference for T bridge reinforcement and maintenance.关键词
