摘要
进行地震作用下双塔双索面预应力混凝土斜拉桥时程法分析,了解全桥的内力分布情况,评价抗震性能并针对地震作用下结构动力特性提出了设计建议。
The Bridge is designed as a prestressed concrete Cable-stayed structure with two towers and two cable planes. The dynamic characteristics are analyzed and the seismic transient analysis is done according to the current code. The froce distribution is clear and the evaluation of seismic ability of the bridge can be done according to the results of finite element method.
