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,得到了一些大跨屋盖位移风振系数的变化规律。Abstract: 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.
