人行斜拉桥结构有限元分析

Finite element analysis on pedestrian cable-stayed bridge structure

通过对人行斜拉桥进行索力测试,并结合有限元模型对比索力变化情况下结构的响应情况,得出索力变化对结构静力及动力响应的影响,通过快速测定索力并进行有限元计算,进而判定桥梁运营状态。

Through testing the cable tensile force of pedestrian cable-stayed bridge,combining with the reflection condition of finite element model on cable tensile force change,it obtains the impacts of cable tensile force change on structural static force and dynamic force.By fast measuring cable tensile force and carrying on finite element calculation,it identifies the bridge operation condition.
