AI Technical Summary

Technical Problem

The existing methods of anti-collapse reinforcement of steel pipe concrete frames are mainly concentrated at the connection nodes, and the use of right-angle reinforcement plates is easy to break at the bends, and the anti-collapse performance is weak.

Method used

A continuous collapse-resistant reinforcement structure including square steel pipes, steel beams and reinforced plate units is adopted. Steel beams are installed on both sides of the square steel pipes and fixedly connected to the main unit through reinforced plate units to increase bending resistance.

Benefits of technology

Through the design of the reinforced plate unit, the connection strength and bending resistance between the steel beam and the square steel pipe are significantly improved, and the collapse is prevented.

Abstract

The invention discloses an anti-progressive-collapse reinforcing structure and method for a concrete-filled steel tube frame, and relates to the technical field of reinforcing of concrete-filled steel tube frames. The concrete column comprises a square steel tube, a concrete column body is poured in the square steel tube, steel beams are installed on the two sides of the square steel tube and are arranged perpendicular to the square steel tube, and reinforcing plate units are fixedly connected between the steel beams and a main body unit. A traditional right-angle reinforcing piece only depends on the strength of the bent positions when being bent, the bent positions are perpendicular to each other, and the reinforcing piece is prone to being broken off from the bent positions when collapsing, however, compared with a traditional right-angle reinforcing piece, the reinforcing plate unit can greatly improve the anti-bending performance, and the strength of the reinforcing piece is greatly improved. And compared with a traditional reinforcing mode, the peak point load and the corresponding displacement of the steel beam and the square steel pipe are averagely increased by 5.5% and 10.9% after the steel beam and the square steel pipe are reinforced.
