Seismic Performance Evaluation of RCC vs. Steel-Concrete Composite Structures Using STAAD Pro

This study offers a detailed comparison between two structural systems: Reinforced Cement Concrete (RCC) and SteelConcrete Composite (SCC) buildings, with a specific focus on their seismic behavior. Using STAAD.Pro software, seismic analysis was conducted on G+5 structures situated in Seismic Zone III. Parameters such as base shear, displacement, and stiffness were evaluated. The results indicate that SCC structures demonstrate superior seismic performance, exhibiting reduced lateral displacement and base shear along with better energy dissipation. These findings highlight the structural efficiency and potential advantages of composite systems in earthquake-prone regions.
