【摘要】 针对7度设防地区的底部框剪砌体结构,采取不同的剪力墙高宽比,用非线性时程分析的方法,对该结构在不同地震动强度下的地震反应进行分析.对比不同高宽比下该结构的层间最大剪力、各层最大相对位移以及各层最大加速度.结果表明:随着剪力墙高宽比的适当加大,建筑物的地震反应呈现出均匀性减小.更多还原

【Abstract】 This paper researches on the influence of aspect ratio on aseismic behavior of masonry structure with bottom frame shear walls.In view of the masonry structures with bottom frame shear walls in the 7 degree seismic fortification intensity region,the structure’s earthquake responses at various seismic intensities were analyzed by using different aspect ratios and nonlinear time history analysis;and then a comparative analysis was done between the maximum inter-floor shear forces,the maximum relative displacements and maximum accelerations of each floor,at different aspect ratios of the structure.The results show that with the gradual increase of shear walls’ aspect ratio,the building’s earthquake response steadily decreases.更多还原
