        abstract = {Irregular reinforced concrete (RCC) buildings are highly susceptible to seismic damage due to abrupt variations in mass, stiffness, and geometry, which induce excessive lateral displacement and torsional effects. While seismic standards like IS 1893 provide general design guidelines, comparative research on the effectiveness of different bracing configurations for irregular structures remains limited. This study evaluates the seismic performance of a G+15 irregular RCC building—incorporating mass, stiffness, and geometric irregularities—strengthened with three steel bracing systems: X-bracing, V-bracing, and inverted V-bracing.
Using ETABS, it is performed in compliance with IS 1893 to compare braced and unbraced models. Structural responses were evaluated based on story displacement, inter-story drift, and natural time period. Results indicate that integrating steel bracing significantly enhances seismic resistance and structural stability. Among the configurations, X-bracing exhibited superior performance, providing the highest lateral stiffness and the greatest reduction in displacement and time periods. V-bracing and inverted V-bracing also demonstrated effective drift control. These findings offer practical guidance for structural engineers designing or retrofitting irregular RCC buildings in active seismic zones.},
