摘　　要：本文综合采用静力分析法和时程分析法,对预应力单层索网幕墙进行了设计和分析。时程分析法是以风洞试验结果为基础,将风荷载时程作为外施荷载时程作用于有限元模型上,采用瞬态分析方法得出结构的动力响应,从而解决了风振系数无法准确取值的难题。The paper presents the method for designing and analyzing glass curtain wall supported by prestressed single-layer cable net. The static and time-history analysis method are both used. Time-history method is based on the result of wind tunnel experiments. As external load, the time history of wind load is applied to the finite element model. Dynamic response will be acquired by using the method of transient analysis, which solves the problem that the wind fluttering factor can not be accurately valued.
