［摘要］采用層間隔震技術(shù)對某建筑進行加層與加固的減震設(shè)計，并對高位層間隔震結(jié)構(gòu)和加層后無隔震傳統(tǒng)結(jié)構(gòu)進了對比分析，包括反應(yīng)譜和局部非線性多遇地震和罕遇地震作用下的時程分析。分析結(jié)果表明，高位層間隔震結(jié)構(gòu)能明顯減小結(jié)構(gòu)的地震反應(yīng)，改善結(jié)構(gòu)的抗震性能，從而減少底部原有結(jié)構(gòu)構(gòu)件的加固數(shù)量,并且能使結(jié)構(gòu)滿足現(xiàn)行抗震設(shè)計規(guī)范要求。最后還提出采用高位層間隔震技術(shù)時電梯井的處理方法，可供相關(guān)工程設(shè)計參考。

Abstract:The earthquake reduction design of a structure reinforced by story isolation technology was carried out. The comparative analysis of the high-lever story isolated structure and the non-isolated structure adding stories was conducted through the response spectrum analysis as well as the local nonlinear time history analysis under the condition of the frequently earthquake or rare earthquake. The results show that the high-lever story isolation technology can obviously reduce the seismic response and improve the seismic behavior of the structure. Therefore, the number of the reinforced components at the bottom of the structure can be reduced while it enable the structure to meet the existing requirements of Code for Seismic Design of Buildings. Finally, a processing method of shear wall core while adopting the high-lever story isolation technology is proposed which can provide a reference for similar engineering structures.
