Static and Dynamic Finite Element Analysis on Structure of Assembled Steel Highway Bridge

为精确计算装配式公路钢桥的静、动态力学特性,利用有限元方法对钢桥结构进行分析。先建立装配式钢桥结构模型,然后基于静力学、振动理论和有限元方法对其进行结构力学性能仿真,并比较不同拼组方式下钢桥的力学性能,为装配式公路钢桥的使用提供指导和参考依据。

In order to calculate static and dynamic mechanical characteristics of assembled steel highway bridge accurately,the paper analyzes steel bridge with finite element method. It firstly establishes assembled steel bridge structure model.Then,it simulates its structural mechanical properties with statics,vibration theory,and finite element method. Finally,it compares the mechanical properties of steel bridge under different combinations,which can provide guidance and reference for applying assembled steel highway bridge.
