摘要: 简支箱梁桥是一种应用广泛的桥梁,但其应力、应变和挠度的计算比较繁琐。在分析桥梁横向分布影响线和偏载系数的基础上,提出了一种基于平面杆系有限元软件的较为简便的计算方法,对该计算方法进行了实例计算,计算结果表明该方法正确且实用。

关键词: 箱梁桥, 横向分布影响线, 偏载系数

Abstract: 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.

Key words: girder bridges, transverse load-distributing influence lines, eccentric loaded coefficients
