Abstract
The Steel-concrete composite constructions are commonly used in modern construction. Due to its several advantages over RCC and steel structures, composite structures consisting of steel and concrete are particularly popular. The structural members of RCC buildings are heavier and have larger cross-sections. Steel constructions have higher deflections and flexibility than concrete structures, helping resistance to earthquake loads. In composite structures, the appropriate qualities of RCC and steel structures are blended. The composite structures facilitate lower costs, quick construction, and fire protection, among other attributes. Present study covers comparison of high-rise (G+8) RCC and composite structures in seismic zone IV considering the provisions of IS: 1893 (Part1) -2002. The seismic behaviour of frames created using the suggested methodology is assessed using ETABS software's nonlinear time-history analysis and the results are compared using various parametric data, for structures in all sorts of building frames, maximum storey displacement, storey stiffness, storey drift, fundamental time periods, base shear, and weight are determined. The steel-concrete composite frames, along with RCC and steel constructions, are best suited for medium to high rise buildings, according to comparative research.
