Problems solved by technology

[0005] In fact, due to the large yield bearing capacity of the traditional buckling-constrained brace, when subjected to a small earthquake, the braced member cannot enter the buckling state in time, and cannot exert the energy dissipation capacity of the member
Moreover, the stiffness of the component degrades quickly after buckling, and the bearing capacity is greatly reduced.

Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with specific embodiments.

[0029] A two-stage anti-buckling energy-dissipating brace, which is used to reduce the damage of the beam-column connection under the action of the earthquake, and reduce the damage and destruction of the main structure caused by the earthquake, including the support core plate 1, the buckling restraint member 2, the positioning steel plate 3, Cementitious material 4, connecting nodes 5 and high-strength bolts 6. Wherein, the outer ends of the two supporting core plates are respectively connected to the frame structure through a connecting node. Specifically, one end of each connecting node is rigidly connected (such as welding) to the end of the supporting core plate, and the other end is connected to the main structure High-strength bolts are used for connection. In this embodiment, the length of the support core board on the left side is greater than the lengt...

Abstract

The invention relates to a two-level buckling preventing energy dissipation support, and belongs to the technical field of civil engineering structural projects. Two supporting core plates, a bucklingrestraint component, a positioning steel plate and two connecting joints are included. The two supporting core plates are arranged in the same linear direction and connected through the positioning steel plate. The other ends of the two supporting core plates are connected with the body structure through the two connecting joints correspondingly. The buckling restraint component is in cup joint to the exteriors of the two supporting core plates. The positioning steel plate is connected with the buckling restraint component. Gel materials are poured into the parts between the buckling restraint component and the supporting core plates. The bearing force of one supporting core plate is smaller than that of the other supporting core plate. A two-level buckling preventing energy dissipation method is further related. Application of the two-level buckling preventing energy dissipation support is further related. By means of the two-level buckling preventing energy dissipation support, thetwo-level buckling preventing energy dissipation method and the application of the two-level buckling preventing energy dissipation support, the structure safety can be improved, the construction costof an engineering structure is reduced, and the structure anti-disaster capability is improved.

Description

technical field [0001] The invention relates to the technical field of civil structure engineering, in particular to the technical field of energy dissipation and shock absorption in engineering structures. Background technique [0002] With the development of my country's industrialization construction, resisting the action of earthquakes and mitigating the damage to structures caused by earthquakes has become a key task in the design of modern engineering structures. [0003] At present, the earthquake resistance of building structures generally adopts increasing the damping of the structure and setting up isolation layers to dissipate the energy of the earthquake on the structure. The traditional buckling-resistant bracing members are mainly composed of internal core materials, external restraint Composed of sliding interface, it has both the functions of ordinary steel support and metal energy dissipation damper. When a strong earthquake occurs, buckling-resistant brace...
