摘　　要：针对在门窗和幕墙工程中广泛使用的铝合金E形薄壁截面构件,文中通过分析不同长细比构件在受弯整体屈曲时挠度-弯矩曲线、轴向应变-弯矩曲线的特征和联系,探讨了在挠度-弯矩曲线无极值时,铝合金E形截面构件受弯整体屈曲临界弯矩的确定方法。Aluminum alloy E-section thin-walled beam which commonly used in windows,doors and curtain walls engineering,The characteristics and relationships between deflection-moment curve and axial strain-moment curve according to the analysis of different slenderness ratio bearing overall flexural buckling. The determination method of the critical moment of aluminum alloy E-section beam exerted on overall flexural buckling was discussed while its deflection-moment curves had no extremum.
