Abstract

Rapid urbanization and increasing vehicle ownership have intensified the demand for efficient multilevel parking facilities in urban areas. This study analyzes the seismic performance of a G+7 multilevel parking structure using Reinforced Cement Concrete (RCC) and Steel-Concrete Composite construction in ETABS-2015. The analysis considers dynamic loading conditions for a site at Chhatrapati Sambhajinagar (Paithan Gate), following IS 1893:2002 seismic provisions. Structural performance is evaluated based on storey displacement, storey drift, modal participation ratio, and fundamental time period. The results indicate that the composite structure performs better than the RCC structure by exhibiting lower displacement, reduced storey drift, higher modal participation, and greater stiffness while satisfying IS 456:2000 serviceability limits. The study concludes that steel-concrete composite construction is a more efficient and reliable solution for multilevel parking structures, offering improved seismic performance and supporting sustainable urban infrastructure development.
