| 摘 要： | 本文采用双自由度非比例阻尼振动模型描述基础隔震体系，用拉普拉斯变换方法获得其地震时域响应的近似解析解，借助于应谱理论分析了非比例阻尼对隔震体系中的上部结构层间最大剪力及隔震层最大位移等响应值的影响，探寻了隔震系统最佳阻尼比的取值范围。

| Abstract: | The base isolation structure is simulated by a 2 -DOF non-proportionally damped vibration system, an approximate analytical solution in time domain is derived using Laplace transfrom method. The effect of non-proportional damping on the maximum shear force in the superstructure and on the maximum isolator displacement is analyst based on response spectrum theory, and the optimum range for isolator damping ratio is studied. |
