        abstract = {Soft-storey reinforced concrete (RC) buildings are highly vulnerable to seismic forces due to stiffness irregularity at lower levels. This study evaluates the seismic behavior of G+20 and G+30 RC buildings with soft-storey conditions using advanced retrofitting techniques such as Buckling Restrained Braces (BRB), Shape Memory Alloy (SMA) systems, steel bracing, and Flag-shaped shear walls. Numerical modelling and response spectrum analysis were performed in ETABS 21 as per IS 1893:2016 provisions. Parameters such as storey displacement, inter-storey drift, stiffness, and time period were compared for normal and retrofitted models. Results indicate that retrofitting significantly improves seismic performance by reducing drift and displacement while enhancing stiffness and energy dissipation capacity. Among all techniques, Flag shear walls and BRB systems showed superior performance in controlling soft-storey effects.},
