基础隔震结构的能量分析
|
摘要
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 seismic 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.
