摘　　要：本文针对在门窗和幕墙工程中广泛应用的铝合金E形截面构件,使用非线性有限元数值计算结果,拟合出构件受弯整体稳定系数实用计算公式。与英国规范BS8118相比,计算公式简洁,计算结果偏于安全。This paper is working on the E aluminum alloy members, which are usually applied to doors project, windows project, and curtain wall engineering. The practical formula for calculating the integral stability coefficient of the member in bending is fitted according to the result of nonlinear finite element analysis. Compared with the calculation results of BS8118, the formula is simple, the results should be safe.
