摘要
研究了风致响应的频域分析方法,对脉动风作用下结构的风致响应计算理论,静力等效风荷载的表达,计算风致响应时结构参振模态数的确定等问题进行了讨论。根据研究结果编制了随机振动风振系数计算程序,并采用所编程序实际计算了航海博物馆玻璃幕墙索网结构工程,可为分析类似工程提供参考。
The method of wind-induced response in frequency domain was analyzed. Theory of wind-induced response under fluctuating wind, equation of equivalent static wind load, determining of modal number when calculation wind-induced response, were discussed. The software of calculating of random vibration wind vi- bration coefficient was composed. Cable-net glass curtain wall of Maritime Museum was analyzed using the software. The analysis result can be taken as a reference for similar project.
