Behavior of Headed Stud Shear Connectors in Composite Beam
Publication: Journal of Structural Engineering
Volume 131, Issue 1
Abstract
In composite beam design, headed stud shear connectors are commonly used to transfer longitudinal shear forces across the steel–concrete interface. Present knowledge of the load–slip behavior and the shear capacity of the shear stud in composite beam are limited to data obtained from the experimental push-off tests. For this purpose, an effective numerical model using the finite element method to simulate the push-off test was proposed. The model has been validated against test results and compared with data given in the current Code of Practices, i.e., BS5950, EC4, and AISC. Parametric studies using this model were preformed to investigate variations in concrete strength and shear stud diameter. The finite element model provided a better understanding to the different modes of failure observed during experimental testing and hence shear capacity of headed shear studs in solid concrete slabs.
