摘要
利用大型动力分析有限元软件ANSYS建立框架—剪力墙结构和框架结构模型,通过对两模型的模态分析和地震时程分析,分别得到固有频率、顶点位移时程曲线、层间位移时程曲线、层间位移角,并对它们进行对比分析。经分析比较可知:框架—剪力墙结构的自振周期较小、动力特性较好、框架—剪力墙结构中的剪力墙在结构上部对水平顶点位移限制较少,从而能为结构进行合理的设计提供参考。
Using large finite element software ANSYS,the model of frame-shear wall and frame structure are established.The natural frequency,vertex displacement curves,curves of interlayer displacement,story drift are obtained by the comparison of the two models analysis and seismic time-history analysis.The result shows that:the frame-shear wall has less vibration period,better dynamic characteristics,and the frame-shear wall structure in the upper part of the structure has fewer restrictions on the horizontal top displacement,so it can provide a reference design for the structures.
