A buckling restrained brace includes an elongate, hollow sleeve, an elongate yielding core extending substantially through the length of the sleeve, and a buckling constraining element between the yielding core and the inner surface of the hollow sleeve and spaced apart from at least one surface of the yielding core, leaving a gap therebetween. The buckling constraining element may be spaced apart from and, thus, the gap may exist between two or more surfaces of the yielding core. Additionally, an inner sleeve, or liner, may be positioned between the buckling constraining element and the yielding core, with the liner being spaced apart from at least one surface of the yielding core. The buckling restrained brace is useful in absorbing loads, such as seismically induced loads, that are exerted upon a steel frame. |
