In this study, an experimental and numerical analysis of the bond-slip model is made on timber-to-timber bonding connections. The variables examined in this study are the types of adhesives used for bonding, the length of adhesion, and the types of reinforcement used to increase the adherence to the adhesion surface. Two different types of adhesives were used namely polyurethane and epoxy. Three different bonding lengths of 180, 250, and 350 mm were chosen as the bonding length. For each variable, four different test specimens were produced and tested under axial tensile force as a nonreinforced reference test specimen and aluminum, fiber, and steel net type as a reinforced bonding strength. In the experimental study, a total of 24 test specimens were tested and the bond-slip behavior of the timber connections and changes in the axial strain values along the timber adhesion zone were measured. By interpreting the experimental results, a bond-slip model is proposed for the timber bonding connections. In this proposed bond-slip model, the effects of the variables examined in the experimental study are interpreted. In this study, the most successful bond-slip behavior and load-carrying capacity have shown in the test specimen, which is reinforced with steel material reinforcement mesh, using epoxy adhesive, and 350 mm adhesion length. By using the experimental results, the bond-slip behavior is verified by numerical modeling with ANSYS software, and a finite element model was formed.
