【摘要】 对学校工程实例建立隔震结构模型,对结构地震地震反应进行数值模拟,分析隔震结构模型的层间位移、位移角、楼层剪力等地震反应特征参数;对隔震结构和非隔震结构的地震反应进行对比分析,隔震结构的层间位移、层剪力等抗震性能明显优于非抗震结构;对ETABS和PKPM两种有限元软件进行隔震结构数值模拟对比分析,PKPM隔震模拟计算结果和ETABS计算结果差异较小,PKPM对隔震结构的数值模拟结果准确,精度高,满足对工程隔震结构的设计要求,为研究隔震结构数值分析技术及隔震结构设计提供有用参考。更多还原

【Abstract】 A school building isolated structure mode was established,Numerical analysis of seismic analysis of school building was carried out in the computer. Floor deformation,floor shear force,angle of displacement etc. was anal sized. Seismic response of both isolated structure and nonisolated structure were compared as well. Seismic response of isolated structure is obviously better than the nonisolated structure. Finite element program ETABS was also used to Authenticate PKPM analysis results after being compared. The result is that program PKPM is able to simulate the isolated structure accurately as well. The result of the numerical analysis is useful for the study of isolated structure analysis and design.更多还原
