Abstract: Steel-concrete-composite buildings are formed by connecting the steel beams with concrete slab or profiled deck slab with the help of mechanical shear connectors so that slab and beam act as a single unit. In the present work, options of construction of (B+G+11storey) commercial building, situated in Kolhapur, with steel-concrete-composite and RCC are studied and compared with each other. Equivalent linear Static Method of Analysis explained in ETABS version 15 software is used and results are compared for different parameters. Comparative parameter includes roof deflections, base shear, storey drifts, for the building and axial forces and bending moments for column’s and beams at different level. It is observed that steel-concrete-composite building is found to be more safe and economical and better option.
