摘　　要：以清华大学游泳馆点式玻璃建筑设计为背景,对点式玻璃建筑中玻璃自重对两种常用的柔性支承系统的动力特性的影响进行了研究。对比分析了考虑玻璃自重与不考虑玻璃自重在矢跨比和拉索预应力变化时柔性支承体系动力特性的差异。同时,对比分析了两种情况下两种常用柔性支承的风振响应的谱分析。This paper analyzed influence of the glass mass on dynamic performance of two normal kinds of point supported glass curtain wall flexible supporting systems.It contrasted supporting system's dynamic performance with consideration of the mass of glass to the performance without consideration of the mass of glass.It also investigated and contrasted the change of system's dynamic performance as well as the wind vibration response under change of height-breadth ratio and scale of the pre-stress in the cable with consideration of the mass of glass to these without consideration of the mass.
