Embodiment Construction

[0013] A beam-column joint suitable for a square steel pipe column, comprising: a lower square steel pipe column 1 and an upper square steel pipe column 5, a dog-bone short I-steel cantilever 4 is arranged on the lower square steel pipe column 1, The end of the upper square steel pipe column 5 is connected with a lower flange 2, and the end of the upper square steel pipe column 5 is connected with an upper flange 6 that can match the lower flange 2. Holes match the interpolation section 3 with transverse stiffeners, and the upper square steel pipe column 5 is sleeved on the interpolation section 3, and the lower flange 2 and the upper flange 6 are fastened and connected by bolts. There is a gap of 2-3 mm between the outer side of the interpolation section and the inner side of the square steel pipe column.

[0014] After the upper square steel pipe frame column 5 is hoisted in place, it is temporarily fixed after being socketed with the present invention through the node inter...

Abstract

The invention discloses a beam-column joint suitable for a square steel pipe column, comprising: a lower square steel pipe column and an upper square steel pipe column, a dog-bone short I-steel cantilever is arranged on the lower square steel pipe column, The end is connected with a lower flange, and the end of the upper square steel pipe column is connected with an upper flange that can match the lower flange. The inner section of the rib, and the upper square steel pipe column is sleeved on the inner section, and the lower flange and the upper flange are fastened and connected by bolts. The invention effectively realizes the outward shift of the plastic angle of the node domain, improves the secondary seismic performance of the node domain, and simplifies the construction technology of the beam-column connection of the steel frame.

Description

technical field [0001] The invention belongs to the technical field of design and construction methods for joints of square steel pipe columns and I-shaped steel beams in steel frame structures in the field of civil engineering, and in particular relates to a beam-column joint suitable for square steel pipe columns. Background technique [0002] In the steel frame structure, the connection methods of square steel pipe columns and I-beams include column through-type, beam through-type and partition through-type. At present, there is no technology similar to the present invention in China. In recent years, the requirements for anti-seismic structures have increased dramatically. "Strong nodes and weak members" is an effective means to improve the overall seismic performance of frame structures, but it is difficult to achieve this requirement in the actual design and construction process. The main reason is that plastic hinges are easy to form in the joint area, and the struct...
