Abstract:

The main motive behind the composite construction is to make two different materials of different properties to combine together to resist the externally applied load. An experimental investigation was carried out with 6 simply supported beam specimens to understand the flexural behaviours. Out of the 6 beams two beams were composite beams and the rest of the four beams were composite beams with 2 different type of shear connectors. The cross section of the beams were kept such that, span to depth ratio is 8. The grade of concrete used was M30 and the grade of steel used is Fe415. The connection between the steel and the concrete section was provided using C-shear connectors, Stud-shear connectors. The beam specimens were tested by subjecting them to two point loading and the cracking load, load-deflection behaviour, ultimate load and failure pattern of the beam specimens were studied. The experimental results indicate that, the load carrying capacity of the composite beams was increased by 20%. The mid-span deflections at ultimate load for the composite beams were reduced by 50% when compared to control beams. It was observed that, the steel-concrete composite beams failed due to shear-compression failure in the shear span.
