双塔斜拉人行桥力学性能分析

Analysis on Mechanical Performance of Double Tower Cable-stayed Pedestrian Bridge

采用MIDAS/CIVIL有限元软件,对一主跨81m的双塔斜拉人行桥进行分析,计算其静力、动力作用下的力学性能,验证方案的合理性。同时对照国内外规范,对主桥进行舒适度分析,为该类人行天桥设计提供参考。

The analysis on a double tower cable-stayed pedestrian bridge with a main span of 81m is made by using MIDAS/CIVIL finite element software,and its mechanical performance under static and dynamic action is calculated,so as to verify the rationality of the scheme.At the same time,the comfort level of the main bridge is analyzed according to the specifications at home and abroad,so as to provide reference for the design of this kind of pedestrian bridge.
