Comparative study on RCC and Steel-Concrete Composite Building using Linear Static Analysis

Steel-Concrete composite constructions are nowadays very popular owing to their advantages over conventional Concrete and Steel constructions. Concrete structures are bulky and impart more seismic weight and less deflection whereas Steel structures instruct more deflections and ductility to the structure, which is beneficial in resisting earthquake forces. Composite Construction combines the better properties of both steel and concrete along with lesser cost, speedy construction, fire protection etc. Hence the aim of the paper is to compare seismic performance of a 3D (G+5) story RCC and Steel-Concrete Composite building frame situated in earthquake zone IV. All frames are designed for same gravity loadings. Beam and column sections are made of either RCC & Steel-concrete composite sections. Equivalent static method is used for seismic analysis. ETAB2015 software is used and results are compared. Comparative study concludes that the composite frames are best suited among concrete constructions in terms of materials and weight with better seismic behavior.
