PULL-OUT STRENGTH OF MORITISE-TENON JOINT WITH PIN SUBJECTED TO BENDING MOMENT

In case of constant bending moment

Abstract

To investigate the failure mechanism and structural performance of mortise-tenon joints subjected to tensile force under a constant bending moment, pull-out tests of mortise-tenon joint specimens under bending moments were carried out. It is found from the tests that the pull-out strength of a joint, subjected to a damage limit bending moment, increased by comparison with a case of free bending moment. In the case of a safety limit bending moment, the tensile strength was reduced due to bending failure of the tenon. The failure mechanism was also discussed using FEM and macro models.
