摘　　要：以清华大学游泳馆点式玻璃建筑设计为背景 ,在点式玻璃建筑中两种常用的鱼腹式柔性支承系统动力特性研究的基础上 ,运用AR法对脉动风荷载进行了模拟 ,将风荷载导入ANSYS对鱼腹式柔性支承体系的风振响应进行了时程分析。分析了支承体系的风振系数 ,并研究了预应力和矢跨比对风振响应和风振系数的影响。Based on the studies of self vibration of flexible support system for point supported glass curtain wall, this paper investigates its wind vibration response with ANSYS.The pulse wind load is determined and the time process curve of pulse wind load by AR method is simulated.The transient analysis of the support system is done with the time process curve.This paper also investigates the influence of concentrative qualities,prestressed tensile force of the cable and rise-to-span ratio of the system on the wind vibration response performance and the wind vibration factor of the system.
