摘要: 在模型试验的基础上,运用SAP 2000软件对纯框架结构模型、内嵌式摇摆墙框架模型和外挂式摇摆墙框架模型进行静力非线性分析。结果表明:内嵌式摇摆墙与外挂式摇摆墙加固框架的抗震性能在结构的刚度、抗震承载能力、损伤特征、层间变形及变形集中程度等方面均有不同。摇摆墙与框架的连接方式不同对结构的抗震性能有明显的影响。

Abstract: On the basis of model test,the nonlinear static analysis of frame structure model,frame structure with bulit-in swaying wall model and frame structure with external swaying wall model was carried out through the software SAP 2000. The results showed that both frame structure with bulit-in swaying wall and frame structure with external rocking wall seismic performance had difference in the structural stiffness,seismic bearing capacity,damage characteristics,interlayer deformation and the deformation intensity. The kinds of the connection between swaying wall and frame structure had remarkable influence on the seismic performance of the structures.
