Abstract
Disclosed are an all-steel double-plate self-resetting buckling-restrained brace and a method, which belong to the technical field of building construction. The brace comprises two energy-dissipating inner core plates, a peripheral frame restraining component, two 5 force transferring steel plates, two end plates, stiffening plates and a plurality of resetting ribs. The above-mentioned structure is combined by welding and riveting. After the energy-dissipating inner core plates bear force and deform, the relative movement between the force transferring steel plates and the peripheral frame restraining component drives the relative distance between the two end plates to become large so that the resetting ribs are 10 elongated under tension or compression states to achieve a self-resetting function. The problem of too large residual deformation of the existing traditional structure with a buckling-restrained brace component under the action of a medium earthquake or a great earthquake is solved. The post-earthquake maintenance and the reconstruction cost are effectively reduced.
Description
ALL-STEEL DOUBLE-PLATE SELF-RESETTING BUCKLING-RESTRAINED BRACE DEVICE AND METHOD
BACKGROUND
Technical Field
The present invention relates to an all-steel double-plate self-resetting buckling-restrained brace device and a method, in particular to an all-steel double-plate self-resetting buckling-restrained brace suitable for use in the field of buildings.
Related Art
After the great Hanshin earthquake in Japan and the Northridge earthquake in the United States occurred, engineers realized that the buckling-restrained brace component has excellent energy dissipation and vibration damping performances and were introduced in a number of projects in Japan and the United States. In China, buckling-restrained brace systems have been used in many buildings in recent years.
Generally, a buckling-restrained brace consists of energy-dissipating inner core plates, a peripheral restraining component and an unbonded structural layer. Under the action of a small earthquake, the energy-dissipating inner core plates of the buckling-restrained brace component are in an elastic stage and provide lateral stiffness for the main body structure; under the action of a medium earthquake or a great earthquake, the energy-dissipating inner core plates of the buckling-restrained brace component are in a yield stage firstly, and a large amount of seismic input energy is dissipated. So that the original way of energy dissipation of plastic hinges at both ends of the main body structure is converted into a way of integrated energy dissipation of the buckling-restrained brace component, and thus the main body structure can be better protected.
However, the buckling-restrained brace component is a metal damper that dissipates energy by the yield of metal, thus resulting in production of very large residual deformation after medium or great earthquakes. And the traditional buckling-restrained brace usually adopts a reinforced concrete peripheral restrained section and a steel and concrete 1 composite peripheral restrained section, thus resulting in various problems such as difficult control of machining accuracy and heavy workload of wet work.
In recent years, there are very few researches of domestic and foreign scholars on an all-steel assembly-type self-resetting buckling-restrained brace; therefore, the industrialized fast and integrated production of the steel-structure self-resetting buckling-restrained brace are not really achieved.

The energy-dissipating inner core plate is a linear single steel plate, or the energy-dissipating inner core plate is a gradual changing staging dog-bone-shaped plate of which the section of the middle inner core plate part is less than that of each of the connector parts at the two ends.
The rubber plates are 1 to 2 mm thick.
The stiffening plates are welded between the connector parts at the two ends of the two energy-dissipating inner core plates in a fitting way, a notch for accommodating the stiffening plate is formed in the head part of the web plate of the peripheral restraining I-beam corresponding to each stiffening plate, and a concavely-convexly inserted lateral limit structure is arranged between the bottom of the notch and the end part of the stiffening plate. A rectangular groove is formed in the middle of each end plate, each end plate penetrates along a connecting segment, and the end plates can freely slide in the length direction of the energy-dissipating inner core plates due to no welding between the end plates and the peripheral frame restraining component as well as the force transferring steel plates.
