中文摘要：
抗风设计一直是膜结构设计中的核心问题和难点问题.以Davenport提出的阵风荷载因子法为基础,结合张拉式膜结构的风振响应特点,提出一系列改进措施,初步建立了一种适用于张拉式膜结构抗风设计的实用化方法.采用随机模拟时程分析方法对几种典型形状的张拉式膜结构进行了较为系统的风致动力响应参数分析,总结了结构风振响应的规律.并在此基础上,依据提出的抗风设计方法给出了可供设计人员参考的风振系数取值.
英文摘要：
During the design of tensile membrane structures, wind-resistant design is a significant and complex problem. On the basis of the gust loading factor method introduced by A.G. Davenport, this paper proposes some improved measures according to the wind-induced response characteristics of tensile membrane structures, and gives an applied wind-resistant design method suitable for these structures. Systematic parameter analysis of wind-induced response of several typical forms of membrane structures is performed with nonlinear random simulation method in time domain, and some response rules are summarized. Moreover, a formula of the dynamic coefficient is suggested using the proposed wind-resistant method.
