Abstract
The present invention relates to an axially yielding elasto-plastic hysteresis brace including an H-section steel as a steel core, a buckling-restraining member covering an outer periphery of the H-section steel, an unbonded layer filled between the steel core and the buckling-restraining member, and a square steel pipe covering the outer periphery of the buckling-restraining member for reinforcement. For both ends of the H-section steel, one reinforcing plate is welded to each outer surface of each flange so as to be overlapped therewith. The buckling-restraining member is installed so that each reinforcing plate is inserted to the buckling-restraining member through an end thereof by a predetermined length L. And, where the width of the H-section steel as a steel core is given as B and the height thereof is given as H, an insertion length L of each reinforcing plate is set in a range of 2B≦L≦3B and also 2H≦L≦3H.
