摘要
对多层框架橡胶垫减震结构在弹塑性范围内进行了地震反应的动力分析，介绍了其动力特性，并计算了结构在地震波作用下各层的位移、加速度和剪力等地震反应。从与抗震结构的动力反应比较可见，基础减震作用的效果是非常显著的。还分析了不同场地对建筑物减震效果的影响。这些都为结构设计提供了参考依据。
The dynamic analysis of earthquake response of multistory base isolation structure using rubber bearing is described in elastic-plastic range. The dynamic characteristics of base isolation building is given here. The displacement, acceleration and shear response of each floor under earthquake wave are calculated. Comparing the results with the same kind of anti-seismic structure (the base fixed building), the base isolation system is very efficient. Besides, the influence of isolating effect under the different place soil is analysed. These can provide the reference basis for construction design.
