Heavy type wood frame self-resetting node
The invention relates to a heavy type wood frame self-resetting node. The heavy type wood frame self-resetting node comprises a wooden beam, a wooden column, beam-end energy-consuming profile steel, a node area column reinforced steel plate and prestressed reinforcement, the wooden beam and the wooden column are connected through the profile steel and common bolts, the prestressed reinforcement longitudinally penetrates through the wooden beam and penetrates through the wooden column, and the end, opposite to the wooden beam, of the wooden column is fixed through an anchor, disk-shaped springs and anchor backing plates. According to the heavy type wood frame self-resetting node, higher bending resistance capacity and energy dissipation capacity are achieved, under a medium earthquake or a large earthquake, the pressure stress of one side of the beam end disappears, the beam end is opened, the beam-end energy-consuming profile steel transmits the shear force and provides rotational stiffness, the structure has large deformation but is not damaged, the prestressed reinforcement is located in an elastic state, after the earthquake action, damage and residual deformation do not exist in the wooden beam and the wooden column, under the action of the prestressed reinforcement, the beam end returns back to an initial state, and the ideal effects that the structure is stable under the small earthquake, the structure has the large deformation but is not damaged under the large earthquake, and the structure achieves self resetting after the earthquake are achieved. In the long-time using process, the disk-shaped spring is arranged at the anchor end, and the prestress loss problem caused by wood creep is relieved.
