Abstract

The invention provides a steel structure self-reset beam and column joint connection device, which comprises a steel frame column, a steel frame beam, a connecting assembly, a phased energy-consumingdamper, flange connecting plates, a web connecting plate, prestressed tendons and beam transverse reinforcement ribs. The side face of the connecting assembly is welded to the second side face of thesteel frame column, a first longitudinal connecting plate and a fourth longitudinal connecting plate of the connecting assembly are fixed connected with the two side faces of the steel frame beam through the flange connecting plates correspondingly, the short edge of an L-shaped upper connecting plate of the phased energy-consuming damper is fixedly connected with the first beam transverse reinforcement rib, a folding face lower connecting plate of the phased energy-consuming damper is fixedly connected with a second longitudinal connecting plate of the connecting assembly, a transverse connecting plate of the connecting assembly and the steel frame beam are fixedly connected through the web connecting plate, the first ends of the prestressed tendons are fixedly connected with the first side face of the steel frame column, and the second ends of the prestressed tendons penetrate through the second side face of the steel frame column to be fixedly connected with the first beam transverse reinforcement rib and the second beam transverse reinforcement rib. According to a joint method, connecting is convenient, and very high energy consumption and self-reset capability is achieved.

Description

technical field [0001] The invention relates to the field of anti-seismic technology of building structures, in particular to a self-resetting beam-column node connecting device of a steel structure. Background technique [0002] my country is a country prone to earthquakes, and the requirements for the seismic performance of building structures are relatively high, especially for the current high-rise and super high-rise buildings, the problem of seismic resistance is particularly important. In recent years, energy-dissipating and recoverable functional structures have become a research hotspot and have attracted much attention. [0003] Steel structures have the advantages of high strength, good seismic performance, and short construction period, and are widely used in various building structures. The beam-column joint is a key component in the steel frame, which ensures the cooperative work of the beam-column and makes the structure form a whole. However, the traditiona...
