AN EXPERIMENT OF A BUCKLING RESTRAINED BRACING OF LARGE SLENDERNESS RATIO AND THE DESIGN METHOD

Abstract

This paper deals with influence of slenderness ratio about a buckling restrained brace (BRB) experimentally and shows a design method of BRB of large slenderness ratio based on the test results. It is found that a residual deformation accumulate by repetition loading in a BRB of large slenderness ratio. As a result, we suggest the equation to estimate the residual deformation and show that the proposed design method should avoid global buckling.
