| 摘 要： | 建立阻尼器连接的毗邻建筑在地震力作用下的运动方程．在求解地震响应时，地面运动加速度被描述为一随机过程．由于结构系统的非正交阻尼性质，用虚拟激励法在频域内求解结构地震响应．通过分析得出，毗邻建筑用阻尼器连接后，结构的地震响应得到有效控制，较连接前明显改善；选择一定的阻尼器参数可得最佳的减震效果．

DYNAMIC ANALYSIS OF DAMPER CONNECTED ADJACENT BUILDINGS UNDER EARTHQUAKE |
| |
| Abstract: | A formulation of the multi degree of freedom equations of motion for damper connected adjacent multi story buildings under earthquake excitation is presented.The ground acceleration due to earthquake is regarded as a stochastic process,and a pseudo excitation algorithm in frequency domain is implemented in a computer program to handle the non orthogonal damping properties of the system.The effectiveness of joint dampers is then investigated in terms of the reduction of displacement,acceleration and shear force responses of adjacent buildings. |
