| 摘 要： | 本文用随机等价线性化方法探讨了相邻结构之间用粘弹性阻尼器连接后的非线性随机地震反应，分析发现：在小震作用下，粘弹性阻尼器对相邻结构可以同时达到较好的控制效果；但是在强烈地震作用下，安装粘弹性阻尼器有可能会在减少一个结构的地震反应的同时，增大另外一个结构的地震反应。

| Abstract: | Nonlinear stochastic response analysis of viscoelastic damper-connected adjacent multi-story buildings under earthquake excitation is performed in this paper using the equivalent linearization method. It is found that the use of discrete viscoelastic dampers of proper parameters to link adjacent buildings can reduce random seismic response of either building within a wide range under small earthquake.However, if the earthquake excitation becomes large, the performance of viscoelastic dampers deteriorates and the seismic response of one building may increase while the other building's response may decrease. |
