【摘要】 为研究建造在7度地震区混凝土空心砌块8层大开间隔震房屋的抗震性能,本文利用有限元分析软件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,结果表明橡胶垫能减小上部结构的地震反应,对隔振结构可采取降烈度设计,或者可以减少梁柱的截面尺寸及配筋。更多还原

【Abstract】 In order to study the aseismic behavior of an 8-story,big-bay isolated building with concrete block in seismic regions of intensity 7,a 3-dimensional finite-element model with ANSYS is proposed.Sandwich rubber 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 can decrease intensity,or can decrease the cross-section of the beams and columns and the reinforcement distribution.更多还原
