摘要
异形拱人行桥受力具有自身的特性,以贵阳市图书馆人行桥为工程实例,介绍了该桥的结构设计,采用midas Civil软件建立空间有限元模型,对其结构进行静力、动力及稳定性分析,并总结该类异形拱人行桥的受力特点,以为类似异形拱桥的设计提供参考。
The stress of special-shaped arch foot bridge has its own characteristics. Taking a foot bridge of library in Guiyang as an engineering example, this paper introduces the structural design of this bridge. The spatial finite element model established by Midas Civil software is used to carry out the static, dynamic and stability analysis of its structure. This paper summarizes the stress characteristics of this kind of special-shaped arch foot bridge, which can be referred for the design of the similar special-shaped arch bridges.
