The behaviour and possible failure modes of precast wall panels connection under severe loading conditions remain challenging to achieve a reliable connection. Furthermore, the interaction between precast wall panels' interfaces in terms of shear-slip relationship due to adhesion, friction, clamping stress, and dowel action is a complex phenomenon. In this paper, a 3-dimensional nonlinear finite element model was developed to simulate the shear-slip behaviour due to the interaction between the concrete-to-concrete interface of precast wall panels numerically using Abaqus Software and validate the experimental findings of previously published research work. The concrete-to-concrete interface was reinforced with steel bars crossing the shear plane. The constitutive law of materials for concrete and steel, concrete-to-steel bond-slip relationship, and interaction of concrete-to-concrete interfaces are considered. The bond-slip law was employed for the steel bars crossing the shear plane, while a simplified stress transfer approach using perfect bond was considered for the horizontal and vertical reinforcements embedded in both wall panels. The monotonic loading was applied as a displacement control parallel to the shear plane of connection interfaces. This research work will also provide a simplified methodology for incorporating the bond-slip behaviour when modelling the precast wall panel connection under monotonic loading using the connector approach. The purpose of this study is to contribute to a better understanding of simulating the shear-slip behaviour due to the interaction between concrete-to-concrete interfaces with steel reinforcement of precast concrete wall panels under direct shear loading. The essential findings of this study are that the finite element obtained results agreed well with the experimental findings in terms of load–displacement response, and the failure model associated with the connection is a ductile bending failure in the dowel action. The stress distribution of the reinforcing steel bar with different spacing configurations exhibits similar trends along the steel bar.
