摘要
本文利用改进的随机振动离散分析方法计算悬索体系在风荷作用下的方差响应，并由之定义其风振系数，最后对一椭圆形双曲抛物面索网体系进行了数值分析，给出了位移风振系数．
In this paper, the improved discrete analysis method for random vibration is used to calculate the mean square response of the cable roof structures subjected to random wind excitation and the dynamic coefficient for wind-inducing vibration is defined. Furthermore, an analysis of a cable roof structure is made and the dynamic coefficient of displacement is given.
