摘要
膜结构因为其自重轻、刚度小、自振频率低的特点被广泛应用于大跨度建筑结构,也因为如此,膜结构成为对风荷载高度敏感的结构。针对目前膜结构的风振响应分析发展状况,本文对膜结构的风振系数和体形系数的确定做了初步探究和总结。
With light mass, small stiffness and low natural frequency, fabric structures are used to applying to large - span structures and they are sensitive to wind. According to the development of the future wind - induced response, this paper introduces and summarizes the way of calculating on dynamic coefficient and shape factor.
