3.2. Failure Modes

4. Conclusions
- The effects of glue and testing methods on withdrawal resistance of the M&T joint were statistically significant. The withdrawal resistances measured by the tensile method were higher than those measured by the compressive method, no matter whether the joints were glued or not.
- The withdrawal resistance of the M&T joint increased gradually in line with the growth of the tenon member length based on the finite element method.
- The compressive method proposed has an advantage in measuring the true withdrawal resistance of the M&T joint, while the tensile method suited to measure the withdrawal resistance of T-shaped samples for comparative experiments.
