Seismic Soil–Pile–Structure Interaction Studies on High-Rise RC Framed Structure Resting on Pile Groups
Infrastructure will play a vital role in the growth of developing nations like India. Pile foundations in soft soil deposits have increased significantly as a result of the scarcity of land and the need for high-rise structures. Soil–structure interaction is often omitted in conventional design practices considering the base as fixed, which can lead to an underestimation of forces and displacement throughout the system. This study aims to investigate the influence of the length of the pile to diameter ratio (L/d) and embedded length to length of pile ratio (Lb/L) incorporating soil–structure interaction (SSI) using a numerical tool SAP2000. The seismic analysis of a 25-storey high-rise building has been performed using response spectrum analysis for zone V as per IS 1893: 2016 to assess the seismic response of superstructure consisting of lateral displacement, inter-storey drift, base shear, and column moment. A parametric study has been carried out for different L/d and (Lb/L) ratios such as 30, 24, 20, and 0.042, 0.083, 0.125, and 0.167. The numerical results show that the pile foundation with less L/d and Lb/L ratio offers the least lateral deformation, inter-storey drift, base shear, and column moment.
