摘　　要：为了研究在体系之间附加阻尼器的相邻结构的减震性能,文中以两相邻单自由度体系(2-sdof)为算例模型,以两结构的位移响应传递率为性能指标,分析了在结构间分别附加黏滞阻尼器以及金属阻尼器时对应的附加阻尼器阻尼参数与结构参数之间的关系,并通过理论推导得出最佳阻尼参数与结构参数之间的关系.根据得出的最适阻尼公式,研究了在体系间同时附加这两种阻尼器时对应的位移响应.最后通过位移响应曲线对比分析了分别附加黏滞阻尼器、金属阻尼器以及同时附加两种阻尼器时位移响应之间的关系.In order to study the damping performance of two adjacent structures with attached dampers between them,two adjacent single degree of freedom systems（ 2-s dof） are selected as the example model,displacement responses of structure transfer rate as the performance index,and the relationship between the damping parameters of the additional dampers and the structural parameters is analyzed. The relationship between optimal damping parameters and structural parameters is obtained by theoretical deduction for two cases where the viscous dampers and metal dampers are attached to the system,respectively. According to the optimal damping formula,the corresponding displacement response of the structures is studied when the two dampers are attached to the system together. Finally,the displacement responses are analyzed for structures to which viscous dampers,metal dampers are attached separately and two kinds of dampers are attached together by comparison of the displacement response curves
