  • Abstract:
  • Reinforced Concrete (RCC) structures have long been the preferred choice in the Indian construction sector due to their cost-effectiveness and ease of construction. However, with the growing demand for high-rise buildings and enhanced seismic safety, steel–concrete composite systems have gained increasing acceptance because of their favorable strength-to-weight ratio, improved ductility, and superior performance under lateral loads. This study investigates and compares the seismic behaviour of a G+11 storey RCC frame and an equivalent composite frame structure located in Seismic Zone III. Both structural models were designed to resist identical gravity loads, with beam and column members modeled either as RCC or composite sections. Seismic analysis was carried out using the Response Spectrum Method in ETABS, in accordance with IS 1893:2016 provisions. Key parameters considered in the comparative evaluation include fundamental natural time period, storey displacements, storey drift, base shear, storey mass, and overall stiffness characteristics. The results indicate that the composite structure exhibits a lower seismic weight, reduced displacements and inter-storey drifts, and a shorter natural time period compared to the conventional RCC structure. These characteristics collectively demonstrate the enhanced seismic performance and stability of composite frames. The findings emphasize the potential of composite construction as a viable alternative to traditional RCC systems in earthquake-prone regions, offering engineers a practical basis for selecting structural systems that ensure safety, efficiency, and resilience in high-rise construction.
