Calculating Method of Eccentric Loaded Coefficients of Simple Supported Girder Bridges with Plane Finite Bar Elements

Though simple supported girder bridge is used widely,the calculation of its stress,strain and displacement is complex.Based on the analysis of transverse load-distributing influence lines and eccentric loaded coefficients,a relatively simple calculating method is proposed in virtue of plane finite bar element software,and then an example is taken to calculate.The results of calculation confirm that this method is right and feasible.
