为简化屈曲约束钢板剪力墙钢框架的设计过程,提出了两元件宏观单元模型,对屈曲约束钢板剪力墙-钢框架的力学性能进行模拟。基于理论分析与试验数据,得到了宏观单元模型中剪切弹簧的骨架曲线、滞回规则和弯曲弹簧骨架曲线,并将上述各项参数值与试验值进行了对比,同时还将采用宏观单元方法建模的数值模型结果与采用精细有限元方法建模的模型结果进行了对比。结果表明:理论推导得到的各项参数值与试验值吻合良好;采用2种不同方法建模的数值模型结果基本一致;该宏观单元模型的各项参数取值准确,并且能够精确反映该类结构的真实力学性能。

In order to simplify the design process of buckling restrained steel plate shear wall-steel frame, a macro element model called two-spring model was proposed, and the mechanical properties of buckling restrained steel plate shear wall-steel frame were simulated. Based on the theoretical analysis and experimental data, the skeleton curve and hysteretic rule of the shear spring, along with the skeleton curve of the bending spring, were obtained. The above parameter values were compared with the experimental results. Furthermore, the numerical results which were obtained by the macro element model method were compared with those obtained by refined finite element method. The results show that the parameter values obtained by theoretical deduction are in good agreement with the experimental data. The results of the numerical models built by two different methods are basically consistent. The parameter values of the macro element model are accurate, and the real mechanical properties of the structure can be accurately reflected.
