Analysis and Design of a Composite Structure Against RCC Steel Structure

Abstract

Steel-concrete composite construction means steel section encased in concrete for columns & the concrete slab or profiled deck slab is connected to the steel beam with the help of mechanical shear connectors so that they act as a single unit. In this project, steel-concrete composite with R.C.C. and Steel options are considered for comparative study of G+4 storey residential building which is situated in earthquake zone IV. Equivalent Static Method of Analysis is used. For modeling of Composite & R.C.C. structures, STAADPro.V8i software is used and the results are compared; and it is found that composite structure are more economical. The use of Steel in construction industry is very low in India compared to many developing countries. Experiences of other countries indicate that this is not due to the lack of economy of Steel as a construction material. There is a great potential for increasing the volume of Steel in construction, especially the current development needs in India. exploring Steel as an alternative construction material and not using it where it is economical is a heavy loss for the country. Also, it is evident that now-a-days, the composite sections using Steel encased with Concrete are economic, cost and time effective solution in major civil structures such as bridges and high rise buildings.
