Abstract

Due to local topography the construction in hilly areas is usually limited to adoption of either a step-back or step back-setback buildings. These irregular configurations permit columns of varying heights to rest at different foundation levels on sloping ground leading to greater torsion and shear during earthquakes. As a result soil structure interaction must be suitably considered from design point of view. This paper investigates the seismic behaviour of multi storey buildings on sloping ground considering soil-structure interaction. A ten storey reinforced concrete structure with and without elevation irregularities are analyzed for different soil conditions using finite element software SAP2000 and results are compared with respect to top storey displacement, time period and base shear. Equivalent static analysis is adopted in the study and results indicate that model M-3 is the most preferred configuration in hilly regions.
