| 摘 要： | 基于系统的振动微分方程,用数值方法求得隔震结构的加速度反应衰减比。采用Ansys7.1程序中已有的单元,通过结构实例分析,计算采用传统抗震结构和隔震结构的加速度反应衰减比,说明合理选取隔震结构的刚度和阻尼的重要性,为隔震结构工程设计提供了合理方法和理论依据。

| Abstract: | On the basis of the vibrational equations,the ttenuation ratio of acceleration reaction is studied with numerical value method.System is established by the Ansys 7.1.As a example with frame structure at first two stories ang basement isolation is analyzed,the ttenuation ratio of acceleration reaction is calculated.It is shown that inflexibility ang damp of base isolation structure is important.It may be used in performance-based design as a simple ang effective tool. |
