Abstract

The invention discloses an assembled frame structure beam-column energy-consumption connecting key. End plates include the first end plate and the second end plate which are parallel to each other inthe vertical direction; the first end plate and the second end plate are detachably fixed to a frame concrete beam and a frame concrete column correspondingly; steel tube concrete connectors are perpendicularly fixedly arranged between the first end plate and the second end plate; the steel tube concrete connectors include the first steel tube concrete connector and the second steel tube concreteconnector which are parallel to each other in vertical direction; webs are vertically disposed between the first steel tube concrete connector and the second steel tube concrete connector; and the webs are perpendicularly welded and fixed to the steel tube concrete connectors and the end plates. The two steel tube concrete connectors and the webs are arranged between end plates, and then the energy-consumption connecting key is formed; the end plates and the steel tube concrete are combined to form the connecting key so as to improve the bearing force as much as possible, the steel tube concrete has high plastic deformation and energy-consumption property after yielding; and the end plates are detachably fixedly connected to the frame concrete beam and column, and timely replacement and repair of the energy-consumption connecting key are guaranteed.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a beam-column energy-dissipating connection key of a prefabricated frame structure. Background technique [0002] In the prefabricated reinforced concrete frame structure, the part where the prefabricated beam and column members are connected is called the beam-column node, also called the node core area, which is the key part of the main structure. Beam-column joints are in the stress state of combined bending moment, shear force and axial force in the structure; they mainly cooperate with beams, columns and other components to form an overall structure to work together to resist external loads and maintain structural stability and safety. Therefore, the mechanical properties of beam-column joints directly affect the seismic performance of the overall structure. In order to achieve the anti-seismic fortification goal of "not damaged by small earthquakes and not collap...
