中文摘要：

在等效线性化的基础上，推导了消能装置连接的2单自由度相邻结构体系在金井清谱激励下的随机响应计算公式，研究了该减震体系的适用范围，认为该体系宜在于结构频率相差较大且地面运动的能量分布较为分散时采用；通过128个非线性时程分析的实例，对该结论进行了验证．同时考察了消能装置等效刚度和等效阻尼对减震效果的影响，得出结论：消能装置的等效刚度宜选择较小值，等效阻尼存在最优范围，并非越大越好。

英文摘要：

On the basis of equivalent linearization, this article deduced a numerical formula to compute the random response of adjacent buildings linked by energy dissipating devices under the disturbance of kanai-Tajimi spectra, and investigated the application scope of this seismic resisting system. The results show that this system can be adopted when the frequencies of two sub-structures are obviously different and the earthquake records have a broad range of frequency contents, which has been proved by 128 instances of nonlinear time history analyses. It also investigated on the control effect of equivalent stiffness and equivalent damping of linker elements, and got the conclusion that it is better to choose dissipating devices with small equivalent stiffness and there is an optimal scope for equivalent damping.
