Seismic Soil-Structure Interaction (SSSI) is an important aspect in the satisfactory long-term performance of buildings. Assessments of seismic demand of the buildings supported over rigid/fixed base are more well established. Due to the reduction in flexural and torsional stiffness, irregular structures are more vulnerable to damage during seismic disturbance. The present paper investigates the effects of SSSI for irregular building supported on pile foundation. This study utilizes three-dimensional numerical approach to investigate the seismic response of a mid-rise building. Two different configurations of plan irregularities and two recorded ground motions are being considered in the present study. Different parameters such as lateral displacement, interstorey drift, base shear of irregular building considering the effects of SSSI are systematically investigated and reported here. The comparative study amongst different lengths of pile foundation supporting the regular and irregular buildings brings out the importance of SSSI on their performance. Results indicated that considering the effects of SSSI amplifies the lateral displacement, interstorey drift and base shear to a larger extent for irregular building in comparison with regular building supported on pile foundations.
