NUMERICAL INVESTIGATION ON SEISMIC PERFORMANCE OF RC FRAME IN SLOPED GROUND
Due to scarcity of plain ground rapid construction is taking place in hilly areas i.e., on sloping ground. Earthquake is such an unpredictable calamity that it is very necessary for survival to ensure the strength of the structure against seismic forces. Therefore there is continuous research work is going on around the globe, revolving around development of new and better techniques that can be incorporated in structures for better seismic performance. Obviously, buildings designed with special techniques to resist damages during seismic activity have much higher cost of construction than normal buildings, but for safety against failures under seismic forces it is a prerequisite. RCC structures are considered in seismic areas that may be main targets of seismic activities. Due to such conditions now a days there is a heavy demand of earthquake resisting RCC structural design. Not only seismic activities but also due to accidental failures, structure can fail. To analyse RCC structure for earthquake zone, we have to make model using ETABS software which can resist all types of loading such as dead load, live load, seismic load using IS 1893. In this study (G+5), (G+10) and (G+15) storey structures will be analysed by using Equivalent dynamic Response spectrum method used. This structure placed on Plain ground as well as on sloping ground of 100, 200, 300. After analysing models in ETABS the results for Storey displacement, Base shear, Storey drift, Time period and Modal participating factors are then obtained. After observing this result some conclusions are made.
