摘要
针对某人行天桥的颤动问题,介绍了该桥的设计标准,从挠度和振动两方面入手,对该人行天桥进行了结构分析,并通过对桥梁结构的检算,提出了整治天桥病因的方案,得出了该方法经济有效,能彻底解决天桥自振频率上的问题。
According to the trembling problems of a pedestrian bridge, it introduces the designing standard of this bridge. From flexibility and shaking, it analyzes the structure of this pedestrian bridge, and by checking of bridge structure, it brings forward plans to govern this kind of diseases on bridge. Finally, it concludes that this method is economic, effective, and can solve the self-trembling problems fundamentally.
