In a hybrid bridge, the joint of UFC bridge slab and steel girder using headed stud shear connector and non-shrinkage mortar has been developed. Nevertheless, in the real structures, in order to adjust the elevation of the slab, the thickness of the filled mortar is varied, whereas, the shear capacity needs to be ensured. This paper presents a 3D FEM model, which simulated accurately the experimental results. Furthermore, results of a parametric study on shear capacity of the headed stud connection with different mortar thickness and stud height using 3D FEM analysis are reported.
