摘要：

采用谐波叠加法模拟风速时程，将风速时程转换为风荷载时程施于漏斗形膜结构，分析膜结构风振响应，获得结构各区块风致动力放大系数.计算表明：漏斗形敞开式膜结构各节点位移响应较为稳定且具有周期性，速度响应曲线和加速度响应曲线均较稳定；结构表面不同部位的风振响应差别较大，迎风面的风致动力放大系数较高，背风面风致动力放大系数平缓.

关键词: 膜结构, 风速时程模拟, 风致动力放大系数

Abstract:

By using the harmony superposition method (HSM), the wind velocity time history was simulated and converted to wind load time series. Applying the wind load time series to funnel-shaped open membrane structure(FOMS), the structural wind-induced vibration response and the wind-induced dynamic magnification factor were numerically investigated. The results revealed that the wind-induced nodal displacement, the velocity and acceleration responses of FOMS were stable, and the statistics for the wind-induced nodal displacement time history followed the Gaussian distribution. Furthermore, the windinduced dynamic magnification factor related to different parts of the structure varied significantly and the windinduced dynamic magnification factor on the windward part of structural system was greater than that on the leeward part.

Key words: membrane structure, wind velocity time series simulation, windinduced dynamic magnification factor
