摘　　要：建立了考虑轴力变化影响的钢结构杆件的恢复力模型，介绍了模型构成和经试验比较得到的 模型的适用性。采用这一模型，对钢框筒结构进行了多维地震作用下的非线性分析，对这类结构的 弹塑性特征进行了考察。Hysteresis model for steel members with considering axial force change is founded. The outline of the model is described and the validity of the model is shown through experimental research. By this model, non-linear response analysis of steel tube frames against to multi-component earthquake is performed, and inelastic behaviors of the steel tube frames are investigated.

关 键 词：变轴力 非线性地震反应 钢框筒结构 恢复力模型 弹塑性
