摘要
为研究整体装配式剪切墙结构的抗震性能,此次研究制作出12 层装配整体式剪切墙和现浇墙,并通过ABAQUS软件建模,利用振动台进行地震试验,测得建筑在模拟地震中的裂缝形态、楼层最大剪力、最大位移角、结构延性系数等数据.试验结果表明,装配整体式剪切墙与现浇墙的抗震性能相近,两者均符合国家标准,且前者在弹性阶段和塑性阶段产生的最大渐层位移角分别为 1/1036 和 1/130,延性系数为 3.21,数据证明,装配整体式剪切墙在高层建筑中的抗震性能更优.
Abstract
In order to study the seismic performance of the integrally assembled shear wall structure,the 12 storey assem-bled integral shear wall and cast-in-situ wall are produced in this study.The model is modeled by ABAQUS software and the seismic test is carried out by shaking table.The crack shape,maximum shear force,maximum displacement an-gle and structural ductility coefficient of the building in the simulated earthquake are measured.The test results show that the seismic performance of the assembled integral shear wall is similar to that of the cast-in-place wall,and both meet the national standards.The maximum gradual displacement angles of the former in the elastic stage and plastic stage are 1/1036 and 1/130 respectively,and the ductility coefficient is 3.21.The data show that the assembled inte-gral shear wall has better seismic performance in high-rise buildings.
