Abstract This study proposes an analytical model to predict the flexural behavior of glued-in-rod (GIR) detailed timber beam-to-column connections. The analytical model is developed by considering constitutive law of materials, strain compatibility, and force equilibriym at the section. This model incorporates the nonlinear behaviors of timber and steel reinforcing components, inclduing factors such as reinforcement type, bonding strength, and wood density. Experimental observations were then conducted on GIR detailed timber beam-to-column connections in order to evaluate their structural performance subjected to flexural loadings. To verify the accuracy of the suggested analytical model, the moment-curvature relations and important damage phenomenon according to loading states were compared with those of experimental results. The suggested analytical model can accurately simulates the moment-curvature relation, resulting a close match with experimental results in terms of initial elastic stiffness, secant stiffness, moment capacity at elastic limit, and maximum moment capacity. Based on this result, the suggested model can be utilized to optimizing the design and performance prediction of timber beam-to-column connections with GIR details.
