摘　　要：以某8层框架结构为例,使用ETABS软件进行时程反应分析,可以得到考虑土与结构相互作用时橡胶隔震体系、滑移隔震体系等不同模型在第Ⅳ类场地的自振周期、层间剪力、最大位移等情况,得出不同结构的自振周期都有延长,各层位移增大,滑移隔震体系相对于普通结构和橡胶隔震体系而言,剪力和层间位移都大幅度降低,因此在第Ⅳ类场地使用滑移隔震体系效果更好。Taking an8-story frame structure as an example,using etabs software,the vibration period,interlaminar shear and maximum displacement of different models such as rubber isolation system andsliding isolation system under the interaction between soil and structure can be obtained.the results showthat the vibration period of different structures is prolonged,each layer displacement increases,and thesliding isolation system is significantly reduced compared with common structure and rubber isolationsystem,and the effect of sliding isolation system is better at the class iv site.
