Abstract : This paper describes damper system design for pounding between existing building and its extension. In this system, passive viscous dampers are used by which the existing building is connected to its extension. To improve the seismic performance of the adjacent buildings, it is necessary to perform sufficient reinforcement in spaces that are already used. In metropolitan cities such as Yangon and Mandalay, these spaces are very limited and are not sufficient. Furthermore, in high-rise buildings, seismic retrofit is much more difficult not only for the above reasons but also because of the difficulties of the construction work and changes in the structural system due to the structural reinforcements. Seismic pounding is defined as the collision of adjacent buildings during earthquakes due to insufficient separation gap between buildings. Pounding Effect between existing building and its extension is studied by non-linear dynamic analysis. Firstly, the required ground motion records are obtained from PEER ground motion database by using input parameters. Secondly, the adjacent two buildings are separately analysed and the maximum displacements of two buildings at connecting corner points are resulted. Thirdly, two buildings connected with dampers are continuously analysed for pounding effect by using non-linear time history analysis. Finally, it is observed that the maximum displacements between two adjacent buildings by using dampers are reduced as compared to the case of the independent system. Keywords- Maximum Displacement, Non-linear Time History, PEER Ground Motion Database, Seismic Pounding, Viscous Damper
