This paper presents a three-dimensional (3D) non-linear finite element (FE) analysis for a precast reinforced concrete (RC) beam-column joint under monotonic static load using ABAQUS software. The constitutive material laws for concrete and steel, the concrete-concrete interaction, the concrete-steel bond-slip at beam component, and the modelling of the linking parts of discontinuous main bars were considered in this study. The FE model was validated with experimental results from another published research. The validated FE model was then utilized to parametrically investigate the effect of the connection location and bar linking parts within the connection zone on the load capacity and failure patterns of the beam-column joint. Results demonstrated that the FE model is able of reproducing an identical behaviour to the experimental test. Further, locating the precast connection away from the column face can result in increased load capacity and minor damage at the connection region. Additionally, the bar link parts had a minor effect on load capacity but a significant impact on stress and crack distribution. Overall, the developed FE model can replicate the structural behaviour of the precast beam-column joint connections under the static load, and therefore, it can be used as an effective tool for examining the connection design parameters.
