A beam-column energy-dissipating connector based on a U-shaped plate and its construction method

Abstract

The invention discloses a beam-column energy-dissipating connector based on a U-shaped plate and a construction method thereof. It is arranged between the column side end plate and the beam side end plate, and the beam side end plate is fixed to the beam end of the prefabricated beam through prestressed tendons; two energy dissipation units are symmetrically arranged on the upper and lower sides of the connecting section steel, and one end of the energy dissipation unit It is fixedly connected to the end plate on the column side, and the other end is fixedly connected to the beam end of the prefabricated beam; the connecting plate on the column side and the connecting plate on the beam side in the energy dissipation unit are arranged vertically The ends are fixedly connected, and the U-shaped plate is arranged between the connecting plate on the column side and the connecting plate on the beam side; the present invention utilizes the plastic deformation of the U-shaped plate to dissipate energy, and the energy consumption through the yield of the joints has the effect of vibration reduction; the beam side The end plates are fixed to the prefabricated beams through prestressed tendons. Under the action of prestress, residual deformation can be reduced and the seismic performance of the structure can be effectively improved.

Description

Technical field

[0001] The present invention belongs to the field of prefabricated building technology, particularly relates to a U-shaped plate-based beam and column energy-consuming connector and construction method thereof. Background

[0002] With the rapid development of prefabricated buildings, dry connection technology has received widespread attention because it does not require a large number of wet operations on site to meet the development concept of green environmental protection, energy saving and high efficiency of prefabricated buildings; The part where the prefabricated beams and columns are connected is called the node core area, which is the key part of the main structure under force, and is in the force state of bending moment, shear force and axial force composite action in the structure.

[0003] At present, most of the node parts are weakened to control the plastic hinge occurs at the end of the beam when the earthquake occurs, and the seismic force is dissi...
