SEGMENTAL BUCKLING-RESTRAINED BRACE FOR SEISMIC REINFORCEMENT OF STEEL STRUCTURE

摘要

The present invention relates to a segmental buckling-restrained brace for the seismic reinforcement of a steel structure which has a reinforcement material having coupling portions exposed on one side surface thereof and segmented into given lengths so as to surround a core material which is formed of an H-beam, thus facilitating movements and assembly, providing bolt fastening without using a coupling method including welding, and being very easily constructed even during the operation of the steel structure like power facilities. According to the present invention, the brace for reinforcing the steel structure formed by columns and beams includes: the core material formed of an H-beam having a central web and flanges formed vertically on both ends thereof; and the reinforcement material having supporting portions with a L- shaped section, fixing portions bent two times inward perpendicularly from the top ends of the supporting portions, and coupling portions bent outward perpendicularly from the lower side ends of the supporting portions, wherein the fixing portions are fitted to the top end portion of the flanges of the core material, and two coupling portions are coupled to each other and face-contacted with each other to surround the lengthwise center of the core material. The reinforcement material has segmented surfaces segmented at given intervals thereon in such a manner as to be segmented into a plurality of parts, and reinforcement bands having a square sectional shape in such a manner as to be segmented on the lower surfaces thereof and protruding coupling portions bent outward from the segmented portions are coupled to the outer peripheral surfaces of both end portions of the reinforcement material coupled to the core material and to the outer peripheral surfaces of the segmented surfaces of the reinforcement material.;COPYRIGHT KIPO 2014
