ABSTRACT:
The present invention is directed to a brace apparatus having a core member configured to absorb energy generated by seismic or other forces by undergoing plastic deformation. A buckling restraining assembly is included for maintaining the structural integrity of the brace after the core member has undergone plastic deformation. The buckling restraining assembly includes one or more bearings is located proximal the core member. The bearings are adapted to minimize friction between the core member and the buckling restraining apparatus. An air gap is positioned between the core member and the one or more bearings of the buckling restraining apparatus are adapted to prevent bonding of the core member and buckling restraining assembly. Projections are included in the core member of the brace apparatus to minimize movement of the middle portion of the core member relative to the buckling restraining assembly.
