[提要]  点式玻璃幕墙在国内运用越来越广，而现有的幕墙规范(JGJ102-96)对其应力和位移分析没有做出明确规定。为此，从理论上分析了影响点式支承玻璃板承载性能的几个重要因素：连接约束条件、支承点连接方式。运用有限元数值分析的方法重点研究了玻璃建筑技术中带孔点式玻璃孔边缘应力的问题，分别讨论了孔边缘应力集中和孔心边距对玻璃板承载性能的影响，为规范修改和工程设计提供了参考依据。

Point-supporting glass curtain wall have been used more and more widely in China today, but current code (JGJ102-96) of curtain wall doesn't solve the problems of stress and displacement. This paper analyses several factors influencing loading properties of glass monolayer plate, such as connection manners,connection shapes, describes problems of concentrated stress of hole's edge of point support glass in glass buildings, especially the influence of concentrated stress of hole's edge and distance from center to plate's edge on loading property of glass plate, which provides basis for revising code and construction design.
