        abstract = {Past earthquakes have shown that ground motion is the main cause of structural damage and human casualties. Traditional design methods often assume fixed-base conditions where structure rests on rigid foundations ignoring the influence of Soil-Structure Interaction (SSI). This simplification can lead to either unsafe or overly conservative designs especially for tall buildings on soft soils. A more accurate approach requires accounting for the interaction between the superstructure and foundation. This study evaluates the seismic response of a 20-storey asymmetrical reinforced concrete frame supported by a piled raft foundation using finite element analysis in ANSYS. The foundation system includes configurations with single piles and two piles in series and parallel with embedment ratios (L/D) of 10, 15, and 20. Each configuration is analyzed for both parallel and perpendicular orientations relative to seismic loading. The analysis uses an acceleration response spectrum based on the peak ground acceleration of the 2001 Bhuj earthquake. Key response parameters include lateral storey displacement, inter-storey drift ratio, foundation displacement and settlement. Results highlight the substantial impact of SSI, showing that flexible soil conditions significantly affect seismic performance. Incorporating SSI in design ensures safer, more reliable, and resilient structures in earthquake-prone regions.},
