In the modern construction sector, steel-concrete composite deck slabs have emerged as an alternative to conventional concrete slabs nowadays. The composite construction is lighter, stronger and economical when compared to conventional construction method. The longitudinal shear capacity of the slab determines the ultimate load of the composite slab and is the most prominent failure type in composite slab construction. The profile steel sheeting acts as an external tensile reinforcement in the slab. In this experimental investigation, three types of embossments viz., chevron, rectangular and inclined penetrated are introduced for predicting the m-k curve. Totally six numbers of steel-concrete composite deck specimens are used for the study. For each type of embossments, two numbers of specimens were chosen with two different shear span conditions. The specimens are cast using M25 grade of concrete and using 1 mm thickness of profiled steel sheeting to avoid the shrinkage and creep of the concrete, 8 mm diameter of secondary reinforcements are provided (on top of the profiled sheet). The specimens are subjected to static loading and load capacity was found. As per the regulations of Euro-code 4, the m-k method is used to determine longitudinal shear capacity of the deck slabs. The linear regression analysis was plotted using experimental tests data to predict the m-k value.

Abstract
In the modern construction sector, steel-concrete composite deck slabs have emerged as an alternative to conventional concrete slabs nowadays. The composite construction is lighter, stronger and economical when compared to conventional construction method. The longitudinal shear capacity of the slab determines the ultimate load of the composite slab and is the most prominent failure type in composite slab construction. The profile steel sheeting acts as an external tensile reinforcement in the slab. In this experimental investigation, three types of embossments viz., chevron, rectangular and inclined penetrated are introduced for predicting the m-k curve. Totally six numbers of steel-concrete composite deck specimens are used for the study. For each type of embossments, two numbers of specimens were chosen with two different shear span conditions. The specimens are cast using M25 grade of concrete and using 1 mm thickness of profiled steel sheeting to avoid the shrinkage and creep of the concrete, 8 mm diameter of secondary reinforcements are provided (on top of the profiled sheet). The specimens are subjected to static loading and load capacity was found. As per the regulations of Euro-code 4, the m-k method is used to determine longitudinal shear capacity of the deck slabs. The linear regression analysis was plotted using experimental tests data to predict the m-k value.
