        abstract = {This study presents a performance-based seismic evaluation of G+23 high-rise reinforced cement concrete (RCC) and steel–concrete composite structures subjected to nonlinear time history analysis using Bhuj earthquake ground motion. Four structural configurations are analyzed: RCC fixed-base, RCC with Lead Rubber Bearing (LRB), composite fixed-base, and composite with LRB. The models are developed in ETABS with identical geometry and loading conditions. Nonlinear time history analysis is carried out considering material and geometric nonlinearities. Key response parameters such as storey displacement, storey drift, base shear, overturning moment, and time-dependent response are evaluated. The results indicate that base isolation significantly reduces seismic forces while increasing structural flexibility. Composite structures demonstrate superior performance due to reduced mass and improved ductility. The composite structure with LRB shows the best seismic performance, achieving up to 30% reduction in base shear and 40% reduction in overturning moment while maintaining drift within permissible limits.},
