摘要
针对大跨网架屋盖风致振动问题 ,采用时程分析方法 ,在有限元建模的基础上 ,直接采用风洞试验的数据 ,计算了台州市体育中心屋盖结构的竖向位移风振系数 。
Aimed at the wind-induced vibration of the long-span grid roof,based on FEM and the data obtained form the wind tunnel test,an analysis of time-history is used to calculate the wind-induced vibration factor of vertical displacement of the roof for Taizhou Stadium.Furthermore,the changing law of wind-induced vibration factors of the displacement of long-span roofs is also obtained.Characteristics of the dynamic wind-load factor are drawn.
