Double side plate type beam-end anti-torque joint with unilateral bolt connection

Abstract

The invention provides a double side plate type beam-end anti-torque joint with unilateral bolt connection. The double side plate type beam-end anti-torque joint with unilateral bolt connection comprises an H-shaped steel column, side plates and H-shaped steel beams; the two side plates are separately and fixedly arranged on flanges of the two sides of the H-shaped steel column, the two side plates are parallel mutually, and the axes of the side plates are perpendicular to the axes of the H-shaped steel beams; the H-shaped steel beams perpendicularly and fixedly arranged at the positions, located on the H-shaped steel column, of the outer surfaces of the two side plates; and the H-shaped steel beams perpendicular to an H-shaped steel column web plate are fixedly arranged at the positions,located on the two sides of the H-shaped steel column web plate, between the two side plates. According to the double side plate type beam-end anti-torque joint with unilateral bolt connection, physical isolation of the beam columns is achieved by the double side plates, a force transferring path of the beam-end anti-torque joint with double side plate type unilateral bolt connection is changed toenable a plastic hinge to move outside, the force transferring path is changed to enable the plastic hinge to be appear on the beam, and the requirement of ''strong column and weak beam and strong joint and weak member'' is achieved.

Description

technical field [0001] The invention belongs to the technical field of beam-column joints of steel structures, and in particular relates to a beam end torsion-resistant joint connected by double-side plate type single-side bolts. Background technique [0002] In order to meet the needs of strong columns and weak beams, and to move the plastic hinge to the beam, two technical solutions have appeared in recent years: strengthening the column section, such as using inner diaphragms and outer ring plates; weakening the beam section, such as using dog-bone flanges or Drill holes in the beam web. When the plastic hinge moves to the beam end, the local instability of the beam end or the overall instability of the beam may occur. The stability of a beam is related to its critical bending moment, and strengthening the warpage constraint at the beam end is an effective way to increase the critical bending moment of a beam. Welding channel stiffeners at the end of the beam is the mos...

AI Technical Summary

Problems solved by technology

The existing beam-to-column connection technology makes it difficult for groove stiffeners to approach both ends. Even if they can, there is a problem of overlap of weld seams, which makes the stress state of the joint area complex and affects its bearing capacity.
