摘要
随着市域交通的飞速发展,城市人行天桥因其功能特点,需要适应特定的场地环境且兼具一定的景观要求。天桥为梁式体系时宜采用联合梁结构[3]。现结合广州市花蕾路人行天桥设计,介绍一种新型的联合梁人行天桥——钢结构槽型梁人行天桥,该天桥方案能较好地适应桥址场地条件,且兼具较好的景观性。通过对该人行天桥的设计方案、计算方法及有限元分析进行论述,为类似的工程提供参考。
With the rapid development of city traffic, the urban footbridge needs to adapt the special site environment and has a certain landscape requirements because of its functional characteristics. The footbridge for the beam system is suitable to use the joint beam structure. Combined with the design of a footbridge in Hualei Road of Guangzhou City, this paper introduces a new type of joint beam footbridge - steel structural U-shaped girder footbridge. This footbridge scheme can better adapt to the site condition, and has the better landscape. This paper discusses the design scheme, calculation method and finite element analysis of this footbridge, which can be referred for the similar projects.
