摘要
对有偏心的单塔基底隔震结构和同基础多塔基底隔震结构进行数值分析,计算结果表明,对有偏心的单塔隔震结构,在地震作用下采用同基础多塔基底隔震结构的形式能大幅度降低结构的扭转反应,因此,条件许可时相邻偏心结构的建筑,采用同基础隔震的形式,对提高隔震效果是有利的。
In this paper,the simulation analyses of eccentric single building base-isolated structures and common-base eccentric multiple building base-isolated structures subjected to seismic excitations are carried out.The results show that the torsional responses of common-base eccentric multiple building base-isolated structures are far less than that of the eccentric single building base-isolated structures.Therefore,if the situations are permitted,the neighbouring eccentric buildings should adopt common base-isolated structures in order to increase the isolated effects.
