Abstract

Among the possible structural damages during an earthquake, the seismic induced pounding also has been one of the commonly observed phenomena. This is because the separation gap between many adjacent buildings is inadequate to accommodate the relative motions, so buildings vibrate out of phase and collides. Despite the fact that the seismic pounding between nearby structures is considered in the codal procurements, the act of development is still an issue in numerous metropolitan zones where the structures are built with no adequate partition separation which brings about their pounding. In this study E-Tabs nonlinear software is used for simulation of adjacent multi-storeyed RC frame buildings of G+14 and G+9 storey, the provisions that may reduce the effects of pounding like the separation distance, addition of shear walls, lateral bracings and variation in storey height of the buildings have been considered for analysis. And the responses like storey-displacement and pounding force by considering both fixed base and base-isolated conditions are arrived.
