This paper presents a comparative analysis between steel and steel‐concrete composite connections with extended end plate. Numerical models were developed using ATENA 3D and calibrated from the results obtained by Figueiredo (2004) – University of São Paulo (USP – São Carlos) ‐ Brazil. A parametric analysis, achieved by varying the diameter for the bolts and the stud bolts, showed that considering the concrete component in the connection increased the joint's stiffness by 41%. In addition, it showed that among all the parameters analyzed the bolt diameter was the most relevant one, capable of altering the characterization of the connection's ultimate limit state.
