Behaviour of Steel–Concrete Composite Beams Provided with Headed Stud Shear Connectors

This paper presents the results obtained from finite element analysis using ANSYS, of a steel–concrete composite beam provided with headed stud shear connectors. The performance of shear connector has been analysed, and an optimum spacing for a particular beam with respect to static load has been identified. Numerical study was carried out to investigate the behaviour of steel–concrete composite beams of different span lengths prepared with headed shear studs of different dimensions at varied spacing of stud connectors. The load–deflection behaviour of steel–concrete composite beams provided with stud spacing of 150, 200 and 250 mm for beam span lengths of 1, 2 and 3.2 m was studied. From the results of numerical study conducted, it has been observed that the deflection increases with increase in span length and stud spacing, while it decreases with increase in stud dimension. Further, it is found that the beams provided with studs at 150 mm spacing possesses more strength compared to other types.
