Joint for connecting buckling-restrained brace, concrete beam and concrete column
The invention discloses a joint for connecting a buckling-restrained brace, a concrete beam and a concrete column; an anchoring part anchored in the concrete beam and the concrete column is composed of two groups of spaced H-shaped profile steels; the H-shaped profile steels and an anchoring plate are welded into a whole one; the internal edge of the anchoring plate id arranged at the external sides of the concrete beam and the concrete column; a joint plate is integrally welded with the anchoring plate; the external end of the anchoring plate integrally welded with the joint plate is lengthened to be longer than the lateral side of the joint plate; and bolt holes for fixing the buckling-restrained brace are formed on the joint plate. The H-shaped profile steels in the joint plate have good stability in a plane and high rigidness and are not easy in instability; the profile steels have big welded areas with the anchoring plate and are not easy to produce pulling/pushing damage; the profile steels have big contact and load-transfer areas with the concrete and are capable of uniformly dispersing the load to the concrete beam; the lengthened parts at two ends of the anchoring plate are capable of effectively avoiding direct extrusion between the joint plate and the concrete, so that the stress concentration is relieved and the service life of the joint is prolonged; the integrality of the concrete beam and the concrete column is not influenced, so that hoops and longitudinal ribs in the concrete beam can be arranged easily; the steel ratio in the joint area of the beam and the column is increased and the strength and rigidness of the joint is improved by the plastic deformation of the beam restrained by the anchoring plate; the whole component can be manufactured in a factory and the construction time is saved.
