Behavior of Connected Tall Buildings Installed with Dampers

Abstract: Tall structures are now a days very popular because of land acquisition problems. A connected tall building generally refers to a skyscraper or high-rise building that is physically connected to one or more adjacent buildings, either through bridges or other structural elements. It gives enhancement of structural performance under lateral loads and also gives horizontal connectivity for users. To control the lateral displacement of a tall structure, various lateral load resisting system and vibration control system need to be adopted. In this paper, tall building with Shear Wall system, and Linear Viscous Damper are compared. Models of 25-storied connected tall buildings is studied with different location of sky bridges and dampers. The buildings are analysed by linear time history analysis, response spectrum analysis and wind analysis and the optimum solution have been derived for better performance of building. It has been observed that the structures connected with Sky Bridge and dampers are found to be more effective in reducing various responses like displacement, acceleration, storey drift etc. Keywords - Connected Tall Building, Shear Wall, Bracing, Damper, Earthquake, Wind
