摘要:
为了克服传统滑移隔震限位装置一滑就限增加上部结构的地震反应的缺陷,使滑移隔震技术在框架结构中得到应用,在研究了U型环限位消能元件的工作性能的基础上,采用有限元SAP2000软件,建立了一种新型具有限位装置的滑移隔震三层框架结构的计算模型,并根据合理的碰撞前后滞回特性,进行了单向和双向地震波作用下的隔震结构分析.计算结果表明,限位装置的刚度对结构碰撞后层间加速度和位移量的变化影响较大;双向比单向地震激励对结构产生的最大基底滑移量要大.随着另一个方向地震烈度的不断加大,结构最大滑移量呈现出先增后减的规律,为滑移隔震在框架结构中的设计提供了理论依据
Abstract:
In order to get over the defects of traditional sliding base isolation structure where the reactions of traditional sliding structure always is increased during the earthquake, and sliding base isolation technology was applied to the frame structure. Based on the research of U work performances of energy-absorbed element, the whole element model of the kind of new sliding base isolation three-storey frame structure with equipment of sliding-limit was established by theSAP2000software.According to reasonable hysteretic mode, the calculation analysis under collision responses were carried out. The calculation results showed that the rigidity of the new sliding-limit had a great influence on the changes of the storey acceleration and displacement after collision. The maximum base sliding displacement of bi-directional seismic action was obviously bigger than that of one dimensional earthquake. With the other direction loading earthquake increasing, the maximum base sliding displacement of the structure proved to be increasing first and is fillowed by a decrease decreasing. Effective theoretical basis of sliding base isolation technology being applied to the frame structure was provided
