Bonded-in rods connections: modeling of mechanical behavior
Résumé
Structural bonding technology has proven to be an economically and attractive connection method in timber engineering. Within old or historical wooden structures, local reinforcement of weak zones is frequently provided by bonded-in rods connections. Despite previous research programs, some design rules, predicting pull out or push out strengths, are available but a common criterion is not proposed yet. The combination of experimental and numerical investigations on small samples leads to a better knowledge of mechanical and fracture behavior of such connections, by assessing stiffness, pull out strength and fracture energy. The main results aim at supplying information relative to the safety prediction of bonded-in rods connections.
