不同地震动作用下隔震结构减震影响分析
Analyses of Mitigation Effects of Isolated Structures to Different Ground Motions
摘要
Abstract
By selecting 13 earthquake waves of different spectra based on ratios of peak ground acceleration to peak ground velocity (PGA/PGV) and using non-linear time-history analysis method, the reactions of multi-story base-isolated structures to different ground motions are analyzed in this paper. The results show that the decreasing amplitude ratio of isolated structures overall increases with increasing of PGA/PGV, but the decreasing amplitude ratio is not totally decided by PGA/PGV, which is also influenced by other parameters.关键词
