BUCKLING-RESTRAINED BRACE FOR SEISMIC REINFORCEMENT OF STEEL STRUCTURE

摘要

The present invention relates to a brace for reinforcing a facility of a power generator or a steel structure of a plant, and more particularly, to a buckling-restrained brace for the seismic reinforcement of a steel structure which has a reinforcement material adapted to surround a core material formed of an H-beam to receive tension thereof as well as the compression thereto to prevent buckling upon compression. According to the present invention, the brace for the steel structure formed by columns and beams includes: the core material formed of the H-beam having a central web and flanges vertically formed on both ends thereof; and the reinforcement material having supporting portions with a L-shaped section, fixing portions bent two times inward perpendicularly from 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.;COPYRIGHT KIPO 2014
