摘　　要：针对铝合金应力-应变曲线无明显屈服平台的特点,使用ABAQUS软件,采用不同材料本构模型,对门窗和幕墙工程中常用的E形截面构件的整体屈曲进行分析。结果表明,三段无硬化本构模型具有计算精度较高、计算结果偏于安全和使用简便适于工程运用的特点。Aiming at the aluminum stress-strain curve have no obvious yield platform characteristics.This paper is using ABAQUS software and different materials stress-strain model,to analyze the overall buckling of E-section members which commonly used in windows,doors and curtain walls engineering.The results showed that three sections of non-hardening stress-strain model has these characteristics：calculation accuracy are higher; the results are somewhat safe and it easy to use for engineering application.
