Experimental study has been conducted on the design of composite concrete slabs and RCC slab. In this study full size simply supported slabs has been designed and tested for flexural to study the bending capacity and vertical shear strength of composite slab and the same is compared with bending capacity of RCC slab. ‘m- k’ method is used for the design of composite slab and experimental test setup has been done by following guidelines given by Eurocode 4 – Part 1.1 and IS 456-2000 is used for design of RCC slab. Six composite slabs are split into two groups of three slabs and tested under static and cyclic loading to get ‘m-k’ values and RCC slab is tested under static loading for flexural. As a result composite slab proved to be more efficient than R.C.C. slab for small scale use.

INTRODUCTION Building construction in our country shows variety of construction material in every region; according to type of building, location of building, function of building different materials has been observed. Reinforced Cement Concrete (R.C.C.) is the most widely used construction material for buildings and steel structures also available in large numbers for industrial buildings. Composite steel-concrete buildings have been observed in industrial areas due to its beneficial properties for optimal design and ease in construction activities for large span constructions. Composite material favorably used for industrial structures/buildings. Composite construction method provides most advantageous construction technique than R.C.C. and steel structures for high rise structures. In Composite construction both materials are fully efficient together which results in the best economic design and in speedy construction. Complex behaviour in composite action of steel and concrete can be overcome if design parameters are properly configured, and thus structure can be highly durable with superior seismic performance characteristics (Panchal and Marathe 2011). Comparative study between R.C.C. framed, steel and composite high rise for their structural performance proved that composite structures provide great economic and efficient design. Fig – 1: Details of Composite Slab For the commercial shops mezzanine floor at proper working level provides additional working space to the user. Generally R.C.C. slab panel is provided for the same in new construction or for the extension for mezzanine floor; but in the construction of mezzanine floor over existing structure will raise the problem to provide proper development length of reinforcing steel. Under the proposed work the design and construction of composite slab is compared with the R.C.C. slab so as to provide the efficient and economical option for mezzanine flooring for small scale use in commercial shops. Already composite structures proved their ability for being safe, serviceable and economical for high rise constructions compared to steel and R.C.C. structures with great ease of construction. This study may provide the guidelines for use of composite slab construction for small scale application.
