摘要
介绍了长治市某储煤棚的结构及外形尺寸,通过风洞试验,确定了风荷载分区平均风压系数,对比分析了基于随机振动理论与基于直接积分两种风振系数的计算方法,指出基于直接积分方法可获取大跨度储煤棚屋盖不同风向角下准确的风振系数。
This paper introduced the structure and dimensions of a coal storage shed in Changzhi,through the wind tunnel tests,determined the mean wind pressure coefficients of wind load partitioning,comparative analyzed the calculation method based on random vibration theory and direct integration two kinds of wind vibration coefficients,pointed out that based on direct integration method could obtain accurate wind vibration coefficient of large span coal storage shed roof under different wind angles.
