Abstract

A buckling restrained brace is for connection between two connecting plates of a framework, and includes a restraining unit and an axial member. The axial member includes a middle section surrounded by the restraining unit, two first coupling sections, and two second coupling sections. The first coupling sections are connected respectively and perpendicularly to opposite longitudinal end portions of the middle section. Each first coupling section has a portion exposed from a respective one of longitudinal ends of the restraining unit, and is formed with a first coupling groove for engaging a respective one of the connecting plates. The second coupling sections are connected respectively and perpendicularly to the opposite longitudinal ends of the middle section. Each second coupling section has a portion exposed from a respective one of the longitudinal end portions of the restraining unit, and is formed with a second coupling groove for engaging a respective one of the connecting plates.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priorities of Taiwanese Application Nos. 099108880 and 099205208, filed on Mar. 25, 2010.BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The invention relates to a buckling restrained brace, more particularly to a buckling restrained brace that is adapted to be connected fixedly between two connecting plates of a framework of a building.

[0004] 2. Description of the Related Art

[0005] A buckling restrained brace is generally used in a steel framework of a building for absorbing vibration energy generated by an earthquake so as to minimize damage to the framework resulting from the shock of the earthquake.

[0006] As shown in FIG. 1, a conventional buckling restrained brace 1 is provided between two connecting plates 14 of a steel framework 13 of a building, and includes an axial member 11 and a restraining unit 12 that surrounds the axial member 11. The axial member 11 has end portions longitudinally oppos...
