A critical aspect of structural engineering in hilly regions, where buildings are subject to unique challenges due to sloped terrain and seismic activity. To investigate the seismic performance of a G+8 reinforced concrete (RC) building on sloped terrains with varying inclinations (0°, 4°, 8°, and 12°). Simplifies seismic forces into static equivalents. Captures dynamic response under seismic loading. A total of 4 models were created, combining different slopes angle considerations. Represents the total lateral force at the base of the structure during seismic events. Expected to vary significantly due to sloping angles. Monitors lateral deflection across building levels, which influences stability and comfort. Alterations in load distribution occur due to the asymmetric configuration of the structure. Structures on soft soil experience notable changes in seismic responses, emphasizing the importance of accounting for SSI during analysis and design. Research underscores the necessity of incorporating SSI effects in the seismic analysis of structures on sloping terrains. The findings highlight the influence of sloped configurations and soil properties on base shear, displacements, and bending moments, urging engineers to adopt advanced analysis methods like RSM for improved safety and performance in hilly regions.
