Claim:
1. A buckling restrained brace for connection between structural members of a building and configured to absorb transient loads applied to the building, the buckling restrained brace comprising: a core rod; an end plate assembly attached to an end of the core rod, the end plate assembly being located at a longitudinal end of the buckling restrained brace; a buckling restraining tube concentrically surrounding at least a majority of a longitudinal length of the core rod and configured to provide lateral support to the core rod to hinder buckling of the core rod upon compressive loading of the core rod; a sleeve member concentrically surrounding an end of the buckling restraining tube, the sleeve member affixed to the end plate assembly; and a spring disposed within the sleeve member, the spring located laterally between the core rod and the sleeve member of the end plate assembly and longitudinal ends of the spring abutting the end of the buckling restraining tube and the end plate assembly of the buckling restrained brace, wherein the sleeve member extends longitudinally from proximate the core rod, along the spring, to one of the longitudinal ends of the spring proximate the end plate assembly.
