摘要
本文将框架-剪力墙结构算例模型中的剪力墙简化为单墙柱模型和双墙柱模型后,采用平面铰接体系利用静力弹塑性分析程序,得出层剪力和层间位移曲线。利用该曲线确定与框架-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。同时与ANSYS所得结果进行比较。考虑结构等效抗侧刚度放大系数的和等效面积增大系数的影响,对该结构进行弹塑性时程分析。结果表明:剪力墙单墙柱和双墙柱模型具有一定的合理性和实用性,利用它可以作偏于安全设计,本文计算方法能为结构抗震初步设计提供一种手段。
This paper simplifies the shear wall as the single wall-column model and double wall-column model.Applied the elastic-plastic static analysis,it gets the layer shear and layer displacement curve with frame-shell wall articulated system. This paper calculates the frame-shell wall structure stiffness of the multi-mass system vibration modal by the curve,and calculates the elastic-plastic seismic response with time-history analysis method.By comparing with the results obtained by ANSYS,it directly gets some useful conclusions;Considering the influence of the structure stiffness magnification factor and area magnification factor,the single-wall column modal and double-wall column modal have certain rationality and the usability.It can be used to bias safe design and can provide a mean for seismic preliminary design of the structures.
