【摘要】 以上海某医院一制剂楼为研究对象,分别采用天然橡胶支座隔震体系和铅芯橡胶支座隔震体系,并对其进行弹塑性时程分析。探究了在多遇地震、罕遇地震作用下两种隔震体系的楼层剪力、层间位移角、顶层加速度以及能量耗散等各项性能指标。结果表明:采取隔震加固技术后各项指标都满足了规范的要求并且使结构具有更好的隔震性能。更多还原

【Abstract】 This article took a preparation building in a hospital in Shanghai as the research object,established a natural rubber bearing isolation system and a lead rubber bearing isolation system,and calculated the elastoplastic time history of these two types of isolation systems.The floor shear force,inter-story displacement angle,top floor acceleration and energy dissipation of the two isolation systems under frequent and rare earthquakes were analyzed.The analysis results showed that all the indexes met the requirements of the codes after the isolation and reinforcement technology adopted and the structure had better isolation performance.更多还原
