桁架结构人行天桥设计与分析

Design and Analysis of Truss Structure Pedestrian Bridge

摘要: 近年来，城市人行桥越来越注重“以人为本”，人行桥设计越来越注重创新设计、景观设计、舒适性设计。城市人行桥已成为集人行过街、商业文化、观光功能于一体的构筑物。城市人行桥多为跨越城市主干路，地铁线路等，跨径较大，本文论述了佛山某大跨桁架人行天桥设计思路、方案比选和几个关键节点设计与分析，为类似工程设计提供参考。

Abstract: In recent years, urban pedestrian bridges pay more and more attention to “people-oriented”, and pedestrian bridge design pays more and more attention to innovative design, landscape design and comfort design. Urban pedestrian bridge has become a structure integrating pedestrian crossing, commercial culture and sightseeing functions. Most urban pedestrian bridges span urban trunk roads, subway lines, etc. with large span. This paper discusses the design idea, scheme comparison and selection and several key node design and analysis of a long-span truss pedestrian bridge in Foshan, so as to provide a reference for similar engineering design.
