摘要
大跨度体育场馆轻质罩棚对风荷载往往比较敏感,风荷载成为此类结构设计的控制荷载之一。为了满足工程设计与试验研究的需要,该文对复杂体型体育馆进行了刚性模型测压试验,同时考虑了风向角对风荷载体型系数的影响,经过计算分析得到了不同风向角下结构表面的体型系数分布。研究结果表明:罩棚顶部大部分区域为负压且顶部的波浪造型对风压分布有明显的影响;同时分析出围护结构风敏感区域及风吸力最大值,对结构抗风设计提供了重要依据。
A large-span stadium light-shed is often sensitive to wind loading,and wind loading is one of the control loads for such structural design.In order to meet the needs of engineering design and experimental research,a rigid model pressure test for a complex gymnasium is carried out through the calculation and analysis for the shape factor distribution under different wind angles of surface structure,considering the influence of wind directions on the wind load shape coefficient.The results show that the most areas at the top of the canopy are negative pressure,and the wave shape at the top has obvious influence on the wind pressure distribution.At the same time,the maximum wind sensitive area and the maximum wind suction value of the enclosure structure are analyzed,which provides an important basis for the wind resistant design of the structure.
