Benefits of technology

[0007]Therefore, the object of the present invention is to provide a buckling restrained brace which can be easily examined after being subjected to shock of an earthquake.

Problems solved by technology

However, once the restraining member is destroyed, the entire buckling restrained brace would be damaged and has to be replaced by a new one, regardless of whether the axial member was damaged by the shock of the earthquake.
Accordingly, the damage examination procedure of the conventional buckling restrained brace 9 is still relatively troublesome.

Embodiment Construction

[0025]Before the present invention is described in greater detail, it should be noted that like elements are denoted by the same reference numerals throughout the disclosure.

[0026]As shown in FIGS. 3 to 5, the first preferred embodiment of a buckling restrained brace according to the present invention is adapted to be connected fixedly between two connecting plates 6 of a framework 5 of a building. The building has a wall structure that includes a pair of spaced-apart wall plates 9 (only one is shown in FIG. 5). One of the wall plates 9 is formed with a through hole 92. The framework 5 and the buckling restrained brace of this invention are disposed between the wall plates 9. The buckling restrained brace comprises an axial member 1, a restraining unit 2, and a plurality of securing units 30.

[0027]The axial member 1 is configured as an elongated steel plate, and includes a middle section 11 extending in an axial direction (L) and having opposite ends in the axial direction (L), and ...

Abstract

A buckling restrained brace includes an axial member, a plurality of restraining members, and a plurality of securing units. The axial member includes a middle section extending in an axial direction, and a pair of coupling sections extending respectively from opposite ends of the middle section and that are adapted to be coupled fixedly to two connecting plates of a framework of a building, respectively. The restraining members extend in the axial direction, and are disposed around and contact the axial member. Each securing unit secures an adjacent pair of the restraining members together. Each restraining member cooperates with an adjacent one of the restraining members to define an opening therebetween through which a portion of the axial member is exposed for viewing.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority of Taiwanese Application No. 100109344, filed on Mar. 18, 2011.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 includes an axial member visible from the outside of a wall structure in which the buckling restrained brace is embedded.[0004]2. Description of the Related Art[0005]Concentrically braced frames are generally used in a framework of a building for enhancing economically the lateral stiffness of the framework to resist lateral force of an earthquake. A buckling restrained brace, which is a kind of the concentrically braced frames, is particularly configured to have a relatively full hysteresis loop for effectively absorbing vibration energy generated by the earthquake so as to minimize damage to the framework resulting from the shock of the earthquake. A conventional buckling re...
