基础隔震结构的能量分析

The energy analysis and design of the base-isolated structure

通过建立有隔震和无隔震的七层框架结构的分析模型,对其分别输入两条典型的地震波进行地震能量反应分析,结果表明隔震结构能较好地满足能量方程,最后以能量分析方法为基础,建立了基础隔震结构体系的能量设计方法。

Based on the introduction of the energy equations and analysis models of base-isolated structures, the analysis models of a seven-floor frame structure are built, and the energy responses of the structure and the effect of seismic isolation bearings are discussed as two typical seis- rnic waves are input. It is concluded that the base-isolated structure can meet the energy equation. Finally, on the basis of energy theory, in this paper, the energy design measures for this kind of structures are founded.
