Structures exposed to earthquake exited vibrations that are damaging to their structures components. Structural pounding is an additional problem that may take place when closely spaced buildings experience earthquake excitation. This phenomenon occurs when, the structures oscillate out of phase due to their different dynamic parameters and the separation is not sufficient. Separation between the structures would avoid the problem; however, for metropolitan cities located in regions of high seismic activity, the need to maximize use of land has lead to inadequate separation often resulting in pounding of adjacent structures during a strong earthquake. The problem is complicated by the fact that, adjacent buildings usually belong to different owners, and in most cases are built at different times with different building code specifications. These buildings have also been designed with different functional objectives that translate into different dynamic characteristics. Many energy dissipation devices are presently being used to reduce both structure vibration and probability of pounding. The aim of this paper is to investigate the optimal seismic response of two adjacent structures via the use of passive energy dissipation devices, in order to minimize the pounding effect. In this work viscous and viscoelastic dampers have been considered as the devices of choice to mitigate the risk of structural pounding. For the best overall system response, efforts have been made to attain the optimal distribution of the viscous and viscoelastic dampers in the adjacent structures. The required number of dampers of known capacity and their optimal placement locations in adjacent buildings are calculated to achieve the maximum reduction in a desired response.
