高层框架──核心筒体减震结构模型试验

SHAKING TABLE TEST OF MODELS OF TALL FRAME-CORE TUBE STRUCTURAL SYSTEM EQUIPPED WITH ENERGY ABSORBERS

通过单层、三层结构模型的动力试验结果，表明在框架──核心筒体结构体系内安装减震器后，减震效果显著．试验与计算结果吻合较好，说明了计算理论的正确性．

n order to compare the dynamic responses of frame-core tube structural systems with and without energy absorbers, we carried out dynamic experiments of single-story and three-story models on a shaking table. The experimental results show thatenergy absorbers can remarkably diminish the dynamic response of the structures, and the use of energy absorbers introduces an effective additional damping into the structural system. The results obtained from the dynamic response analysis are essentially close to those obtained from experiments.
