The base‐isolation system is a very effective technology for earthquake resistance. Nevertheless, it is adverse to the horizontal displacement control of isolation layer and less efficient in reducing the seismic response of the superstructure on a soft soil. The high damping rubber bearings can provide large hysteretic damping and show hardening effect at high shear strains. To explore the applicability of high damping rubber bearings (HDRBs) and the effect of their characteristics on the seismic responses of the structures on soft soils, a six‐story reinforced concrete (RC) building isolated by HDRBs on a soft soil is modeled in SAP2000. By applying deformation history integral type model (DHI model) which can accurately simulate the characteristics of HDRBs and traditional Bouc–Wen model which ignores the hardening effect and high energy dissipation capacity of HDRBs at large shear strains to the bearings separately, seismic responses considering and neglecting the hardening effect and high energy dissipation capacity of HDRBs at large shear strains are investigated. The comparison of the two models shows that the characteristics of HDRBs can effectively reduce the displacement of the isolation layer under extremely strong earthquakes and are conducive to the safety of superstructure under limited earthquake intensities.

应用变形历史积分型模型的高阻尼橡胶支座隔震钢筋混凝土建筑抗震分析。

基础隔离系统是一项非常有效的抗震技术。然而，这不利于隔离层的水平位移控制，并且在降低软土上的上部结构的地震响应方面效率较低。高阻尼橡胶轴承可提供较大的滞后阻尼，并在高剪切应变下显示出硬化作用。为了探讨高阻尼橡胶轴承（HDRB）的适用性及其特性对结构在软土上的地震反应的影响，在SAP2000中对由HDRB在软土上隔离的六层钢筋混凝土（RC）建筑物进行了建模。 。通过应用可精确模拟HDRB特性的变形历史积分型模型（DHI模型）和传统的Bouc–Wen模型，该模型分别忽略了HDRB在大剪切应变下的硬化效应和高能量耗散能力，分别考虑了轴承的抗震性能和研究了忽略大剪切应变下HDRB的硬化效果和高能量消散能力。两种模型的比较表明，在强烈地震作用下，HDRBs的特性可以有效地减少隔离层的位移，有利于有限地震烈度下的上部结构安全。研究并考虑了大剪切应变下HDRB的硬化效应和高能量耗散能力的地震响应。两种模型的比较表明，在强烈地震作用下，HDRBs的特性可以有效地减少隔离层的位移，有利于有限地震烈度下的上部结构安全。研究并考虑了大剪切应变下HDRB的硬化效应和高能量耗散能力的地震响应。两种模型的比较表明，在强烈地震作用下，HDRBs的特性可以有效减少隔离层的位移，有利于有限地震烈度下的上部结构安全。
