| Abstract |
This study used finite element analysis to evaluate the flexural performance of glued-in rod (GIR) timber connections, focusing on the
number of rods, embedded length, specimen length, and cross-sectional size. The model was validated against experimental data and
incorporated a cohesive zone model to simulate adhesive failure. The results showed that increasing the number of rods and embedded length
improved ductility and energy dissipation, especially in long-span specimens. However, in narrower sections, stress concentrations led to
cracking. These findings suggest that GIR connection performance is influenced by multiple interacting factors, providing a structural basis for
more ductile designs in large timber applications. |
