摘　　要：在弯矩 -曲率滞回关系分析的基础上 ,利用数值方法计算方钢管混凝土压弯构件的荷载 -位移滞回关系 ,并对计算结果进行了大量试验验证。在理论分析和试验验证的基础上 ,全面考察构件轴压比、长细比等参数对滞回关系的影响 ,最后给出构件荷载On the basis of analysis of the moment curvature hysteretic behavior,a numerical analysis method is applied to analyze the load deformation hysteretic behavior of concrete filled square steel tubes,and the analytical results agree well with those of the tests satisfactorily.Then the influencing factors to skeleton curve such as axial compression ratio,slenderness ratio are illustrated.Finally,a restoring force model of the load deformation is presented and the corresponding simplified formulae of the parameters in the model and ductility coefficient are proposed as well.
