摘要本文提出对三个相邻结构间连接阻尼装置进行减震控制，推导了其单自由度简化模型随机响应计算公式，同时也给出了多自由度模型的阻尼、刚度等矩阵的构造方法并利用复模态法推导了其随机响应公式；最后对单自由度简化模型的三相邻结构各组合情况的减震效果分别进行了分析，并详细研究一般情况下的多自由度模型的三相邻结构减震效果。经仿真分析表明，三相邻结构控制后与两相邻结构控制所得结果基本相同；在两相邻结构对称而控制无效的情况下，三相邻结构仍可得到较好的控制效果；三相邻结构具有良好的鲁棒性，且对高阶响应峰值抑制明显。

Abstract：An idea of the control among three adjacent structures attached to damping device is presented in this paper. The stochastic response formula has been formulated based on a single degree-of-freedom system model. Further, the formula of the multi-degree-of-freedom system have been deduced based on complex mode superposition method with the corresponding damping coefficient matrix, stiffness matrix, etc, constituted. Finally, the seismic reduction of various combination situations of the single degree-of-freedom system model are analyzed respectively as well as the general situation of multi-degree-of-freedom system. The simulation results show that the seismic reduction effectiveness for three adjacent structures and two adjacent structures are comparable, whereas the former still behave well even if the latter is failed to control themselves because of symmetry. In addition, three adjacent structures are still of favorable robustness and significant suppression for higher-order response peaks under random earthquake excitation.

Key words： adjacent structures complex mode symmetry control robustness
