摘要

采用层间隔震技术对某建筑进行加层与加固的减震设计,并对高位层间隔震结构和加层后无隔震传统结构进了对比分析,包括反应谱和局部非线性多遇地震和罕遇地震作用下的时程分析。分析结果表明,高位层间隔震结构能明显减小结构的地震反应,改善结构的抗震性能,从而减少底部原有结构构件的加固数量,并且能使结构满足现行抗震设计规范要求。最后还提出采用高位层间隔震技术时电梯井的处理方法,可供相关工程设计参考。
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.
