| 摘 要： | 根据隔震层设置的位置不同,常用的隔震结构可以分为顶部减震(TMD系统)、基底隔震和层间隔震.本文借助简化的串联双自由度体系统一地描述了这三种减震控制方式的力学特点,揭示了它们的减震机制.以上、下部分的质量比μ、频率比β和阻尼比等参数,计算了复频响应函数模值的变化曲线,分析了这些动力学参数对隔震系统减震效果的影响.

| Abstract: | Common passive control can be divided into three kinds of top-storey isolation(TMD system),base isolation and mid-storey isolation with the position of isolation storey.A two-degree-of-freedom system is used to describe the mechanical behavior and to reveal isolation mechanism.Taking mass ratio,natural frequency ratio and damping ratio as parameters,the module of complex frequency response function are calculated.The effects of these dynamic parameters on isolation are analyzed. |
