摘要
通过对屋盖的风振响应计算,分析了竖向脉动风和水平脉动风作用下高阶振型对大跨度平屋盖结构风振响应的影响。研究结果为大跨屋盖结构设计和研究提供有意义的参考。
The influence of high order mode shapes on wind-induced dynamic response of long-span fiat roof is discussed. The results can be referred in engineering design and research in wind-induced dynamic response of long-span roof.
