某大跨径人行桁架桥的风振响应研究

Research on wind-induced response of a pedestrian bridge

在风洞试验获得结构表面风压分布和风荷载的基础上,根据精确的CQC计算公式,编制了结构风振响应计算程序,并对桁架桥做了风振响应研究,获得了设计所关心的杆件和节点的响应,对设计起到了指导作用。

On the base of getting wind-pressure placing and wind located in wind cave experience, according to the precise compute formula, works out structure wind-induced response compute program, it researches wind-induced response of the pedestrian bridge gets the pole and node response, so as to guide design.
