Description

TECHNICAL FIELD

[0001] The present application relates to the field of building structures, in particular, to a buckling-restrained brace device. BACKGROUND

[0002] In high intensity areas, the traditional frame structure is often difficult to meet the seismic design requirements due to its weak lateral stiffness. The use of steel braces in the frame structure can greatly improve the seismic performance of the structure. However, ordinary steel braces are prone to instability under the action of earthquakes, especially under moderate or large earthquakes. The instability of the braces leads to the degradation of the overall stiffness of the structure and reduces the seismic performance. Buckling-restrained braces utilize the plastic deformation of the intermediate restrained yield section to achieve hysteretic energy dissipation, and have similar mechanical properties in compression and tension. The energy dissipation mechanism is clear, the performance is stable, the processing technology is mature, and the construction and installation are convenient. For example, Chinese Patent Application No. CN202020323526.4 discloses a buckling-restrained brace device, which includes steel columns and steel beams. Two steel columns and two steel beams are sequentially and fixedly welded end to end to form a "mouth" shape. A support mechanism is installed in a mounting frame and is inclined. The support mechanism includes a diamond-shaped support column, an embedded tube, and a connecting steel sheet. The two end faces of the diamond-shaped support column are fixedly welded with the embedded tubes. The opposite ends of the two embedded tubes are provided with insertion openings. Two connecting steel sheets are inserted into the insertion openings of the two embedded tubes and are fixedly welded with the insertion openings. The two connecting steel sheets are fixedly welded with two opposite corners of the mounting frame. The buckling-restrained brace device has the advantage of preventing the mounting frame from being deformed and causing instability of the structure.

First, the support mechanism is relatively fixed, which is not convenient for adjusting the length of the diamond-shaped support column and is not easy to improve the construction error. Second, it is not convenient to adjust the installation angle of the diamond-shaped support column. When there is a small error, different diamond-shaped support columns need to be replaced, which is not convenient for different sizes of mounting frames, has low applicability, and thus reduces the practicality.
