泉州某高校游泳馆网壳屋盖自振特性及风振响应分析

Mode Shapes And Wind-induced Response Analysis For A Swinmming Hall In Quanzhou

通过对泉州某高校游泳馆网壳屋盖结构的自振特性分析和脉动风振响应计算,此结构振型密集,高阶振型对结构风振响应的影响不可忽视。在福建沿海的网架、网壳结构设计中,风荷载多是此大跨钢结构的控制荷载,特别要考虑脉动风振效应,以保证结构的抗风安全。

By analyzing mode shapes and calculating wind - induced response for A swimming hall, the densely distributed frequencies and the effect of high frequency mode shapes can be not despised. Wind load is often the control load in the area where the wind pressure is very large as Fujian province, the effect of wind - induced response should be considered in design of a latticed shall, to guarantee the safety of structure resisting wind.
