摘　　要：本文是作者几年来在悬索结构抗风设计方面研究成果的总结，内容包括：（１）探讨了悬索结构抗风设计方法的基础思路；（２）以椭圆平面双曲抛物面索网为例，利用随机振动离散分析方法计算了悬索结构的节点位移风振系数和单元内力风振系数，对所得数值结果作了分析，并论证了上述抗风设计方法的可行性；（３）对索网结构控制响应的风振系数进行了参数分析，同时针对椭圆平面、菱形平面双曲抛物面索网两类常用悬索结构，以对结构设计起控制作用的反应指标所对应的风振系数为对象，讨论了荷载参数、几何参数、结构参数的影响。This paper is a comprehensive review of the authors' research work on the wind resistant design of cable roof structures in the recent years, including three parts: (1) The trains of thought of wind resistant design of cable roof structures; (2) In accordance with the hyperbolic paraboloid(H.P.) cable nets with elliptical plans, the aerodynamic coefficients are computed using the discret analysis method for random vibration, which was put forward by the authors, to discuss the feasibility of the train of thought of wind resistant design; (3) In accordance with the H.P. cable nets with elliptical and rhomboid plans, the parameterical analysis of the aerodynamic coefficients for the control indices is carried out, and the values of aerodynamic coefficients used for practical design are offered.
