摘　　要：复杂异形建筑的风荷载大小及其产生的效应无法按照现行设计规范直接确定,通常需要采用风洞试验或数值风洞模拟的方式确定。以某商业天幕单层网壳结构为例,通过数值风洞技术计算结构多风向角下的风载体型系数和风振系数,并讨论风振理论与风振时程分析,为复杂曲面单层网壳结构抗风设计提供参考。The value of wind load and its effect of complex and special-shaped buildings can not be directly determined according to the current design code,and usually it needs to be determined by wind tunnel test or numerical wind tunnel simulation.In this paper,taking a single-layer latticed shell structure with commercial skylight as an example,the wind load shape coefficient and wind vibration coefficient of the structure under multiple wind directions are calculated by numerical wind tunnel technology,and the wind vibration theory and wind-induced vibration analysis are discussed,which provides certain reference for the wind resistance design of the singlelayer latticed shell structure with complex curved surface.
