摘要

为研究建造在7度地震区小型混凝土空心砌块八层大开间隔震房屋的抗震性能,本文利用结构有限元分析软件ANSYS提出了砌块模型的三维有限元模型,在基础与结构物底部模拟夹层橡胶垫,并对其在隔震前后进行了地震反应分析,结果表明夹层橡胶垫能大大减小上部结构的地震反应,上部结构类似于整体平动。
In order to study the seismic behavior of an 8-story,big-bay isolated building with small-size concrete block in seismic regions of intensity 7,a 3-dimensional finte-element model with ANSYS is proposed in this paper.Four sandwich rebber bearings were simulated between the foundation and the bottom of the model structure,and the seismic response analysis is undertaken before and after isolation.The results show that the sandwich rubber bearings can minish the seismic response of the upside structure and the upside structure is alike whole move.
