摘　　要：以方钢管混凝土压弯构件为研究对象,应用可靠度最优化方法,分析荷载偏心距为常量时构件可靠性。将偏心距视为基本随机变量,同时考虑轴向力和弯矩相关性影响下构件承载力的可靠性,得到相关结论。For square concrete filled steel tubular compression-bending member, this paper analyzes the reliability firstly by the reliability optimization method when treating load eccentricity as a constant, then when looking on load eccentricity as a fundamental stochastic variable, moreover when considering the correlation between the axial load and bending moment, and gets some related conclusion.

关 键 词：可靠度 方钢管混凝土压弯构件 承载力 偏心距
