Comparison of Seismic Behavior of Reinforced Cement Concrete and Composite Frame Structure

Composite steel and concrete Constructions are very frequently used and have benefits over conventional Concrete and Steel constructions. Concrete structures are heavy and provide more seismic weight and less deflection whereas Steel structures instruct more deflections and ductility to the structure, which is helpful in resisting earthquake forces. Composite Construction contain the better properties of both steel and concrete along with less cost, speedy construction, fire protection etc. Hence the objective of the study is to compare seismic performance of a multistorey RCC, Steel and Composite building frame situated in earthquake zone V. All frames are designed for same gravity loadings. The RCC slab is used in all three cases. Beam and column sections are made of RCC, Steel or Steel- concrete composite sections. Equivalent static method and Response Spectrum method are used for seismic analysis. SAP 2000 v25.0.0.software is used and results are compared. Cost minimizations based on material cost for all types of structures is determined. The study concludes that the composite frames structures have better than steel and concrete constructions in the parameters of material cost and along with better seismic performance.
