        abstract = {India's high seismic vulnerability often results in substantial structural damage, largely due to the inadequate consideration of soil-structure interaction (SSI) in traditional design methodologies. Conventional approaches typically model the superstructure independently of the foundation and supporting soil, leading to oversimplified and inaccurate assessments of seismic behavior. This study investigates the seismic response of a 20-story (60-meter) reinforced concrete spaceframe by incorporating SSI using response spectrum analysis. The analysis employs ground motion data from the Bhuj earthquake (2001) to evaluate key response parameters, including lateral displacement and inter-storey drift across various floor levels. Results demonstrate that considering SSI leads to a more accurate and realistic representation of structural performance under seismic loading. The present study underscores the necessity of SSI-inclusive designs to enhance the safety, reliability, and resilience of high-rise buildings in seismically active regions.},
