Study on Seismic Demands of Different Asymmetrical RCC Buildings Using Rubber Base Isolator
Abstract
In the present study three structures such as regular and irregular shapes ( L and T ) with base isolation devices are considered such as lead rubber bearings (LRB) are considered in modeling of buildings of height G+10 RCC structures having material properties M35 grade for concrete and Fe500 for reinforcing steel and structures dimensions are length = 7.5x10 m = 75m, width = 4.5x10 = 45m and heights of G+10 is 36 m from the foundation level, the support conditions are chosen to be fixed base and foundation depth is considered as 3.0m below the ground level structures are modeled using ETABS in seismic zones II, III, IV, V as per IS 1893-2002 method used for seismic load generation linear static .the base isolation devices are arranged in storey1 or plinth level in the structures, The results are shown in terms of graphs and tables.
