Background
The traditional mortise and tenon joint is not a rigid joint in general meaning, and the bending resistance of the traditional mortise and tenon joint is related to deformation development. At the initial stage of deformation, the connection between the mortise and tenon joints is weaker, the joint state can be regarded as hinged, and after a certain relative corner is generated between the beam and the column, the mortise and tenon joints are mutually compacted, and the joint begins to have bending rigidity. Under the action of earthquake, due to the relative sliding of the mortise and tenon joints, the earthquake force applied to the top of the structure is small, and a good energy consumption effect is achieved.
