        abstract = {Earthquakes are one of the most destructive natural hazards affecting structures worldwide. The seismic behavior of buildings is significantly influenced by structural configuration, mass distribution, stiffness, and geometry. Plan irregularities may lead to stress concentration and non-uniform structural response, increasing the vulnerability of buildings during seismic events. This study presents the seismic analysis of a Reinforced Cement Concrete (RCC) building with different plan shapes, namely rectangular, L-shape, C-shape, T-shape, and U-shape, using ETABS. An 11-storey RCC building located in seismic zone III is considered for analysis. The Equivalent Static Method is adopted in accordance with IS 1893 (Part 1): 2016. Key response parameters such as storey displacement, storey drift, and base shear are evaluated in both principal directions. The results are compared to assess the influence of plan configuration on seismic performance. It is observed that building geometry has a significant effect on structural response. Among the configurations studied, the C-shape building shows comparatively lower displacement and drift, while the U-shape and T-shape buildings exhibit higher values due to plan irregularity.},
