某大跨度网状吊杆系杆拱桥不同吊杆布置受力特点分析

Analysis on Stress Characteristics of Different Suspender Arrangements of Some Large-Span Network Suspender Tied Arch Bridge

网状吊杆拱桥由于其良好的景观效果及受力性能,所以先后在欧洲、日本及美国等地相继修建了近百座该体系桥梁。近些年随着高性能材料的应用,国内多座大跨度网状吊杆拱桥应运而生。着重研究网状吊杆系杆拱桥,分析不同网状吊杆不同角度布置、不同间距布置下结构的受力特性,探讨合理的吊杆布置形式,为网状吊杆系杆拱桥的设计、应用提供参考。

Due to its good landscape effect&mechanical performance,nearly 100 mesh suspender arch bridges have been built in Europe,Japan&the United States.In recent years,with the application of high-performance materials,many large-span mesh suspender arch bridges have come into being in China.It focuses on the study of mesh suspender tied arch bridge,analyzes the mechanical characteristics of the structure under different angle layout&spacing layout of different mesh suspenders,and discusses the reasonable suspender layout form,so as to provide reference for the design&application of mesh suspender tied arch bridge.
