摘　　要：幕墙玻璃板的常规设计采用线性理论 ,计算虽简单但偏于保守。本文用板壳力学非线性理论对幕墙玻璃中的两类常见力学模型进行了受力分析 ,导出了受载玻璃板的挠度和应力解析式。由该解析式计算出的正应力值比按线性理论计算出的正应力值小。本文算例中 ,当玻璃板呈大挠度变形时 ,二者的正应力值相差近2 0 %。A nonlinear analysis for a glass panel of a curtain wall is presented in the paper.There two types of boundary condition are considered in the nonlinear theory of plates and shells.A linear analysis is employed in the current design for a glass curtain wall.However that is very simple, but it is too conservative.There some examples were shown that a normal stress given by the nonlinear method is a 20% less than that of the linear method while a glass panel emerges with a large deformation.
