摘要
本文以结构动力学基本原理为基础,分析了具有基础隔震结构物在地震反应中的动力性能.文中利用层间剪切模型分别计算基础隔震与基础固定两类建筑物在地震过程中的加速度、位移及层间剪力.计算结果表明,基础隔震能降低上部结构的加速度反应及变形.
This paper analyzes the clynamic performance of foundation-shock isolation structrues under earthguake response according to the basic principle of structural mechanics. The article respectively calaulates the accelcration, displacement and interlaminar shear of foundation-shock isolation and foun-dation-fixed buildings during the period of earthguake by the interlaminar shear mode. The calculating result shows foundation-shock isolation can reduce the accelerating reaction and deformation of upper structures and therefore has a good application value.
