摘　　要：风荷载是大跨空间结构设计的控制荷载之一,因其结构体型复杂,结构表面的风压和体型系数往往难以确定。本文在风洞试验基础上对一倒锥形大跨空间结构的风荷载分布特性进行了研究,并利用有限元理论在时域上计算了该结构的风振系数,为此类结构的抗风设计提供了依据。The wind load is one of the most important loads acting on long-span space structure.It is difficult to determine the distribution of the wind pressure distribution on the structural surface with complicated shape.Based on the wind tunnel test,the distribution characteristics of the averaging and fluctuating wind pressure were investigated.In the meanwhile,it uses the finite element theory in the domain to calculate the wind vibration factors of the structure.The calculated results can be reference for this and other similar structures.
