Calculation and analysis of tall shear wall isolation system and application and research of simplified model

在高烈度区将隔震技术引入高层剪力墙结构中,其目的是在小震烈度下减小上部结构的地震作用力,从而使上部结构层间位移差能够满足抗震规范和设计的要求。在隔震结构体系简化分析模型的基础上,提出了高层剪力墙结构隔震体系的简化计算分析模型。同时用通用有限元分析程序和隔震技术方法分别计算剪力墙结构隔震体系实例的地震反应效应并作对比分析,计算结果表明:所建立的剪力墙结构隔震体系简化分析模型是可靠实用的,可用于高层剪力墙结构隔震体系的理论定性分析和初步设计中的参数拟定,推动隔震体系在高层剪力墙结构中的应用和发展。

The tall shear wall structure in highly seismic region introduced isolation technology, the aim is to re- duce earthquake load under the frequent earthquake, so that the difference of displacement between the upper structure layer meet earthquake resistant code and the design requirements. On the basis of isolation system Simpli- fied analysis model, this article puts forward a simplified calculation model of the tall shear wall isolation system. At the same time we can calculate the shear wall isolation system with general finite element program and this article method, instance of analysis of earthquake-response. The calculation results show that：the simplified model of shear wall struetureg Seismic isolation system is reliable and can be used in the tall shear wall isolation system of the proposed theory of qualitative analysis and preliminary design parameters; It promotes isolation system applica- tion and development in the high shear wall structure.
