摘　　要：对两种常用的点式玻璃建筑柔性支承系统的动力特性进行研究,对比和分析影响这两种系统自振频率和振型的主要因素。在脉动风荷载作用下对系统风振响应进行谱分析,对影响风振响应的特征和相关因素进行研究,为类似结构的动力特性分析提供参考。Two normal kinds of flexible supporting system of the point supported glass curtain are introduced. The mode of vibration and frequency of these two systems and the main factors that affect them are compared and analysed. By pulse wind load the spectrum analysis of wind vibration response of these systems is investigated and the characteristic and relative factors that affect wind vibration response, which can give an example for similar structures dynamic analysis.
