摘要
用有限元方法对一座六跨简支梁桥的横向地震力按全桥模型进行了计算分析．并与两种简化计算方法的结果进行了比较．研究表明：对于简支梁桥的横向抗震计算，应该采用全桥模型计算，我国公路及铁路抗震规范中的简化计算方法存在较多的问题．
A six span simple supported beam bridge is analyzed for lateral seismic response by FEM. The results of FEM are compared with two kinds of simplified methods. The results proved that the entire bridge model should be used in lateral seismic loading analysis of simple supported beam bridge. The accuracy of the simplified methods in China isnt high.
