Advances in moment transferring dvw reinforced timber connections : numerical analyses and verification, Part 2

This study focuses on the numerical simulation of the dvw reinforced timber connection with expanded tubes. In Part 1 it was shown that two connections, acting together in series, have the same rotational stiffness as one separate connection. Numerical analyses presented in this part (Part 2) confirm these findings. Additionally, several failure modes are studied, which can play an important role in the behaviour of the connection such as possible failures of the constituent materials and failure of the bond between the timber and its reinforcement. For evaluating the latter, special attention is given to the type of adhesive, the glue-line thickness and the peak shear stresses. The simulations are validated by experiments.
