Abstract
A steel center axis force member passes through a steel buckling-restriction member. A stick preventing coat is disposed between the surface of the center axis force member and the buckling-restriction member. Thereby, a buckling-restriction bracing member having a narrower body and lighter weight can be provided to facilitate a rapid manufacture with lower cost.
Claims2
A device for bracing a structure, comprising:
- an elongate steel center axis force member of continuous construction;
- said elongate steel center axis force member having opposite ends with bolt-receiving through holes formed therein;
- a pair of steel buckling-restriction members of continuous construction;
- said elongate steel center axis force member disposed in sandwiched relation to said steel buckling-restriction members along substantially the entire length of said elongate steel center axis force member, excepting said opposite ends;
- a nonstick coating disposed between said elongate center axis force member and each steel buckling-restriction member of said pair of steel buckling-restriction members;
- and
- fastening means for fixedly securing said elongate steel center axis force member into said sandwiched relation to said pair of steel buckling-restriction members;
- each steel buckling-restriction member of said pair of steel buckling-restriction members being spaced apart from said elongate steel center axis force member only by a thickness of said nonstick coating.
