摘　　要：对粘滞阻尼器连接四个方形布置的相邻结构的地震反应进行分析,优化了相邻结构间设置阻尼器的阻尼参数。在四条不同地震波作用下,分别对不同质量比和不同刚度比的相邻结构在无阻尼器连接和有阻尼器连接情况下的地震反应进行分析。文中以结构在地震波作用下顶层最大相对位移最小为优化目标。通过试值计算,寻求对应的最优阻尼系数,并对相邻结构质量比、刚度比与最优阻尼系数关系分别进行比较分析,得出最优阻尼系数与质量比和刚度比的两个关系式。最后,用一个算例模型对公式的合理性进行了验证。The seismic responses analyses of four square adjacent structures connected by viscous dampers are carried out,and the damping parameters of dampers installed between adjacent structures are optimized. Under the action of four different seismic waves,the seismic responses of the adjacent structures with different mass ratio and different stiffness ratio are analyzed without damper connection or with damper connection. In this paper,the optimization objective is to get the minimum of maximum relative displacements of the top of structures under the action of seismic wave. The optimum damping coefficient is obtained by the calculation of the trial value,and the relationship between the mass ratio,the stiffness ratio and the optimum damping coefficient of adjacent structures is compared and studied. Two relations between the optimum damping coefficient and the mass ratio or the stiffness ratio are obtained. Finally,an example is used to validate the rationality of the formulas.
