| 摘 要： | 针对框架—自复位墙结构，将自复位墙假定为刚体，框架简化为多自由度体系，得到了“刚体—多自由度体系”简化分析模型，建立了地震激励下的运动方程，给出了相应的Simulink动态仿真模型。针对典型算例，在多条地震波激励下，分别采用该文提出的方法及ABAQUS有限元软件进行了弹性地震响应分析。总体上，二种方法得到的计算结果差别较小，表明该文所建立的简化分析模型具有较高的计算精度，同时具有很高的计算效率，能进一步应用于框架—自复位墙结构的抗震设计。

| Abstract: | A simplified analysis model, namely the rigid body-MDOF system model, for framed self-centering wall (FSCW) structures is proposed in this paper. It treats the self-centering wall as a rigid body and the frame as a multi-degree-of-freedom (MDOF) system. Adopting this model, the governing equations of motion of FSCW structures under seismic excitation were established. The corresponding dynamic simulation model was developed on the Simulink platform. For a typical FSCW structure subjected to several ground motions, elastic seismic response analyses were conducted by both the proposed method and the finite element software ABAQUS. The results obtained from the two methods were generally close to each other. Therefore, the proposed simplified analysis model has a relatively good accuracy and a rather high computational efficiency. It can be further applied in the seismic design of FSCW structures. |
