Abstract

The invention relates to the technical field of building structures, in particular to a novel rotary connection joint unit of an assembly type buckling-restrained brace steel frame structure. The unit aims to solve the problems of action lag of a plastic hinge, poor effect of a strong column and a weak beam, high hysteretic energy consumption capacity, the overall ductility of a structural system and the like of a beam-column joint position in the prior art. A first joint structure assembly is located in a beam-column joint area where a column and a beam are connected; a second joint structure assembly is constructed on the beam so that the beam can form a preset gap in the beam-column joint area, and the preset gap enables the beam located in the beam-column joint area to form a first beam section and a second beam section; and a third joint structure assembly can be clamped on flanges on the upper side and the lower side of the beam so as to fix the first beam section and the second beam section. According to the technical scheme, the overall ductility of the frame beam-column joint structure is high, the effect of a plastic hinge is prominent, and the anti-seismic property is excellent.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a novel assembled buckling-constrained supporting steel frame structure rotation connection node unit. Background technique [0002] Under the current trend, the seismic performance of buckling-resisted braced frame structures has been deeply studied, and attention has been paid to the overall ductility and local ductility of the structure and their interrelationships. The test results show that the additional edge stiffness on the gusset effectively prevents out-of-plane buckling of the gusset. The anti-buckling bracing frame has more stable hysteretic ductility than the traditional special central bracing frame, and the overall structure shows better seismic performance. Buckling braces in buckling braced frames may not exhibit their full ductility capabilities. [0003] In the prior art, the problems existing in the position of the beam-column joint include the h...
