COMPARATIVE EXPERIMENTAL STUDY ON FLEXURAL BEHAVIOUR OF COMPOSITE SLAB AND RCC SLAB

Abstract

This paper is elaborating the comparative study between simply supported RCC slab and profiled steel concrete slab for their suitability at small scale applications like mezzanine flooring. 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.
