A Study on Dynamic Characteristics of RC Buildings on Hill Slopes

Sripriya Arjun | Arathi S ^[8]

Abstract: 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 hence torsionally coupled and are susceptible to severe damage when subjected to seismic action. The columns of ground storey have varying height of columns due to sloping ground. In this study, behaviour of G+3 storied sloped frame building having step back set back configuration is analyzed for sinusoidal ground motion with different slope angles i. e. , 16.7, 21.8, 26.57 and 30.96 using structural analysis tool STAAD Pro. by performing Response Spectrum analysis have been carried out as per IS1893 (part 1) 2002. The results were obtained in the form of top storey displacement and base shear. It is observed that short column is affected more during the earthquake. The analyses showed that for construction of the building on slopy ground the stepback setback building configuration is suitable.
