Abstract

The invention discloses a self-resetting beam-column energy-dissipating connector and a construction method thereof. Between the side end plate and the beam side end plate; two energy dissipation units are symmetrically arranged on the upper and lower sides of the connecting steel; the shear parts and prestressed tendons are arranged between the beam side end plate and the prefabricated One end of the shear is fixedly connected to the beam side end plate, and the other end extends into the beam end of the prefabricated beam; one end of the prestressed tendon is fixedly inserted into the prefabricated beam; Anchored on the beam side end plate; the invention anchors the beam end end plate of the prestressed tendon and the beam-column energy-dissipating connector, which can realize the tensioning of the prestressed tendon in the prefabrication factory, and ensure the self-resetting ability of the component to the greatest extent ; The shear parts can share the shear force and bending moment borne by the prestressed tendons, which reduces the stress loss caused by the deformation of the energy-dissipating connectors.

Description

technical field [0001] The invention belongs to the technical field of prefabricated buildings, and particularly relates to a self-resetting beam-column energy-dissipating connector and a construction method thereof. Background technique [0002] In the prefabricated concrete frame, 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. [0003] At present, the self-resetting ability of the joint is often realized by the unbonded prestressed tendons. Although it can improve the self-resetting ability of the structure after the earthquake, the energy dissipation capacity is weak; This makes the concrete at the end of the beam prone to damage, resulting in the weakening of the flexural performance of the beam-column joint; if only the prestressed tendons are used to resist the bending moment and bear the shear force, it will inevitably bring about a certain amount of stress loss, resulting in ...
