| 摘 要： | 阻尼比是消能减震结构设计的重要参数，对消能减震结构设计具有决定性影响。消能减震结构设汁巾阻尼是时变参数，消能减震结构是非经典阻尼结构。采用复模态设计方法、强解耦振型分解法、基于变形能的等效阻尼法三种方法分别对不同情况的消能减震结构阻尼比进行研究，得到选择消能减震设计疗法和不同方法计算精度的规律，对消能减震结构设计具有参考价值。

| Abstract: | Damping ratio is an important parameter and plays a decisive role in the design of a structure with energy dissipation devices.Damping is time-variable parameter in the structure with energy dissipation devices,the structure is a non-classical damping structure. The damping ratio is studied by the complex mode method, the forcing decoupling method, and the equivalent damping method based on deformation energy.Some rules for choosing the design method and the calculation accuracy of the structure are obtained in this paper, it is of great significance for energy dissipation devices. |
