Analysis of Seismic Behavior of Multistoried R.C.C Building Resting on Sloping Strata under Seismic Load

Abstract

Construction of RC buildings in preferred locations in the north & eastern hilly regions have increased during the last few decades due to urbanization, population increase, and high influx of tourists. The buildings situated in hilly areas are much more prone to seismic environment in comparison to the buildings that are located in flat regions. Structures on slopes differ from other buildings since they are irregular both vertically and horizontally and therefore susceptible to severe damage when subjected to seismic action. The columns of ground storey have varying height due to sloping ground. This paper presents the comparative analysis of various configurations of 15 storied building with to be found on varying slope with different plan and different structural arrangements situated on seismic zone IV. This study compares various reinforced concrete models framed and analysed their response against dynamic loading to identify and struggle the worst possible scenario. The study is carried out for a combination of three different slopes and different building configuration by response spectrum analysis method and various parameters are compared against various constraints.
