Abstract

Braces controlling tension have been used to resist lateral force in most of medium and row-rise steel structures. Providing high stiffness and strength, these steel brace frames are effective to resist lateral force and control story drift. However, the steel braces are subject to compressive load, they experience the deterioration in load capacity due to bending buckling before yield stress and ideal energy dissipation is unfeasible, which causes unstable behavior of the structure. Therefore, this study has to do with a reinforcing method of the compression brace proposed as friction bolt connection. In order to verify the compressive behavior of the reinforced braces, structural performance test was conducted with variables of slenderness ratio and the amount of reinforcement.
