摘要
为更有效地提高框-筒结构的抗震性能,本文提出了在框架与核心筒体之间安装减震器的积极抗震方法。对用于模型试验的减震器进行了静力试验与理论分析,得出了单个减震器的滞回曲线及减震系统 P-Δ关系的计算公式。对安装有该减震器的高层框架-核心筒体结构体系的地震反应进行了理论分析。分别设计、制做了安装与不安装减震器单层框架-核心筒体结构体系的模型,并在振动台上进行了对比动力试验。结果表明:框架-核心筒体结构体系安装减震器之后,框架和核心筒体的最大振幅均有大幅度减小。
In order to increase the seismic resistant ability the efficiency of frame-tube structures,this paperpresents a study on buliding of tall frame-core tube structures with energy absorbers.It presents asingle energy absorber's hysteresis loops and typical force displacement formulate for the energyabsorber system through static experiments and theoretic analyses on the energy absorbers used inthe one-story model experiments.Theoretical analysis of seismic responses to the frame-coretubestructural building equipped with absorbers are made.2 one story models of frame-tube structuralbuilding,with and without energy absorbers respectively,were designed and Constructed.Reso-nance curves of the models were run on the shaking table.It is obviously shown that the amplitude of the model is significantly lower when the model is equipped with energy absorbers
