This study investigates the effect of concrete slab thickness on the behavior of headed shear studs in composite structures. Experimental tests were conducted using single stud connectors embedded in concrete slabs of 150 mm and 200 mm thickness. The results indicate that the shear resistance of the stud is primarily governed by its deformation and failure, rather than concrete crushing. Load-slip behavior analysis revealed a nearly linear, flexible response up to the ultimate load, with failure occurring at the base of the stud shank before the concrete reached its maximum stress capacity. The ultimate load capacity for the 150 mm thick slab was slightly higher than that of the 200 mm thick slab, suggesting that increasing the concrete cover beyond 50 mm has minimal impact on stud performance. The findings suggest that a 50 mm clear cover is an optimal and economical choice, as increasing slab thickness does not significantly enhance stud behavior but substantially raises material costs.
KEYWORDS
The study evaluated the influence of concrete slab thickness on the behavior of headed shear studs through experimental testing. The results indicate that the primary mode of failure was stud fracture at the base of the shank, with no significant contribution from concrete failure. A comparison between 150 mm and 200 mm thick slabs revealed that slab thickness had minimal impact on stud load capacity, with the 150 mm slab even exhibiting a slightly higher capacity. Load-slip behavior remained consistent across both cases, demonstrating that increasing the concrete cover does not enhance stud performance. Consequently, a 50 mm clear cover is recommended as the most efficient and economical choice for composite slab applications, balancing performance and material cost.
