框架-剪力墙结构分析模型的地震响应比较研究

Comparative study on seismic responses of fame-shear wall structure analysis models

将框架-剪力墙算例模型中的剪力墙简化为单墙柱和双墙柱模型后,分别作弹塑性静力分析,得出层剪力-层间位移曲线,确定和框架-剪力墙算例模型相对应的多质点系振动层模型侧移刚度,进行弹塑性地震响应时程分析,并与ANSYS软件直接计算得到的结果进行比较,得出如下结论:采用框架-剪力墙平面铰结体系进行抗震分析,剪力墙单墙柱和双墙柱模型具有一定的合理性和实用性,可作偏于安全设计,能为结构抗震初步设计提供参考.

This paper simplifies the shear wall as the single wall-column model and double wall-column model, and gets the layer shear and layer displacement curve based on the elastic-plastic static analysis. Also, it gains the stiffness of the multi-mass system vibration model corresponding to the frame-shell wall structure, and calculates the elastic-plastic seismic response with time-history analysis method. By comparing with the results obtained by ANSYS, some useful conclusions are gotten. With the frame-shell wall articulated system, the single-wall column model and double-wall column model are reasonable and useful for seismic analysis. It can be used to bias safe design and can provide a method for seismic preliminary design of the structure.
