    摘要:

    基于高烈度地震区建筑隔震方法设计与分析,以某一钢筋混凝土框架结构为例,通过有限元分析软件ETABS对采用橡胶支座的减隔震技术进行动力分析,并对时程分析结果进行比较,结果表明:与抗震框架结构相比,底层隔震框架结构的周期延长,层剪力、位移、底层轴力均变小,从理论上验证采用隔震支座能有效地减小地震荷载对结构的不利影响,提高结构的安全性。

    Abstract:

    Based on the design and analysis of building isolation method in high intensity earthquake area, taking a reinforced concrete frame structure as an example, the finite element analysis software ETABS was used to conduct dynamic analysis of the seismic isolation technology using rubber bearings, and the time-history analysis results were compared. The results show that compared with the seismic frame structure, the period of the bottom isolation frame structure is longer, the layer shear force, displacement, and the bottom layer All the axial forces are smaller, so it is proved theoretically that the seismic isolation bearing can effectively reduce the adverse effects of seismic loads on the structure and improve the safety of the structure.
