Abstract

The invention relates to an energy-dissipation connecting steel structure beam-column joint and a mounting method thereof. The energy-dissipation connecting steel structure beam-column joint comprisesan H-shaped steel column, an H-shaped steel beam connected with the H-shaped steel column through a double-layer web end plate connecting piece, an upper flange connecting plate and a lower flange connecting plate, wherein the upper flange connecting plate and the lower flange connecting plate are used for connecting the double-layer web end plate connecting piece with the H-shaped steel beam. The double-layer web end plate connecting piece of the energy-dissipation connecting steel structure beam-column joint adopts double-layer webs to transfer beam shear force, the upper flange connectingplate and the lower flange connecting plate transfer beam bending moment, an end plate and the H-shaped steel column are connected for transferring force to the column, the force transferring path between components is clear, and the design method is simple and feasible. Meanwhile, an energy-dissipation column and an energy-dissipation plate are equipped, the energy-dissipation connecting steel structure beam-column joint is an effective energy-dissipation beam-column joint, the components can be machined in a factory and spliced on site, and welding in a construction site is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of construction engineering steel structures, in particular to an energy-consuming connection steel structure beam-column node and an installation method thereof. Background technique [0002] Steel structure is one of the commonly used structural forms of modern building structures, which has the advantages of high strength, good deformation, and good seismic performance. In recent years, the state, provinces and cities have issued relevant standards and policies to encourage the development of green prefabricated steel structure buildings to alleviate the current serious environmental pollution problems, energy and material shortages. Beam-column joints are an important part of steel frame structures, and there are generally three connection forms: all-welded connections, bolted-welded connections, and all-bolt connections. Bolted connections commonly include end plate connections, angle steel connections...
