摘要: 现有的玻璃幕墙规范(JGJ102-96)对点式支承玻璃的应力和位移分析尚未作出明确规定。本文在弹性板壳力学的基础上进行相应的受弯分析,针对实际工程给出了简单适用的计算方法,其结果与有限元分析和试验研究结果相吻合。本计算方法简单明了,可为规范修改和工程设计提供必要理论依据。

Abstract: In current design code of curtain walls the problems of stress and displacement evaluation of point-supporting glass curtain wall have not been settled. Based on the theory of elastical plates and shells, the behavior of glass plates is studied and a simple method is proposed. It is shown that the results are in good agreement with finite element solution and experimental data. It is believed that the present method provides a basis for revising the design code.
