SEISMIC ANALYSIS OF FLAT SLAB BUILDING ON SLOPING GROUND.

Abstract

In a developing country like India urbanization and industrialization has accelerated real estate development which leds to scarcity of land. This started the construction of multistorey buildings on sloping ground. Buildings constructed on sloping ground are very irregular and unsymmetrical in vertical and horizontal plane as compared to the buildings on level ground. Also, these buildings on sloping ground require great attention for seismic analysis. The present work studies the behavior of flat slab buildings on sloping ground. For this, G+8 storey 36 different building models with square plan area on sloping ground are considered. The total plan area and mass of the building is kept constant for all models. The sloping angles 0°, 16°, 21° are considered for square plan. The corner and core columns of some models are replaced with shear wall by keeping the mass constant. The response spectrum analysis of all models is carried out using software Etabs17. The study concludes that flat slab building with shear wall at outer periphery of building is preferable than the discontinuous shear wall at core of the building.
