宽幅反对称系杆拱桥力学性能分析与应用

Mechanical Analysis and Application of Wide Anti-symmetrical Bowstring Arch Bridge

摘要:

随着桥梁景观要求的不断提高，系杆拱桥由于其造型适应性强、经济性好等特点而广泛应用，因此对相关类型桥梁的力学分析越来越重要。基于某宽幅反对称系杆拱桥，分别采用MIDAS、ABAQUS有限元软件对该桥进行全桥和局部计算，分析全桥结构强度、变形，并对拱梁结合段等关键构件进行局部分析。结果表明:全桥强度、变形和局部构件强度均满足规范设计要求。

Abstract:

With the continuous improvement of bridge landscape requirements, the bowstring arch bridge is widely used because of its strong modeling adaptability and good economy. The mechanical analysis of related types of bridges is increasingly important. Based on a wide anti-symmetrical bowstring arch bridge, the finite element software MIDAS and ABAQUS are used to carry out the complete and partial calculation of this bridge, and analyze the structural strength and deformation of the whole bridge. And the partial analysis on key components of arch-beam joint sections is carried out. The results show that the strength, deformation, and local component strength of the whole bridge all meet the requirements of the specification design.
