Abstract

The invention discloses a multi-storey high-rise assembly type steel frame structure with a replaceable open-web energy consumption segment. The structure comprises a truss girder and frame columns for supporting both ends of the truss girder. The truss girder includes an energy consumption segment and a non-energy consumption segment; the energy consumption segment of the truss girder does not arrange a web member to be an open-web type, so that the energy consumption is concentrated; two ends of the energy consumption segments of the truss girder are in butt joint with one end of the non-energy consumption segment in a detachable manner so as to facilitate the replacement of the energy consumption segment after an earthquake, and the other end of the non-energy consumption segment of thetruss girder is mounted on the frame column; and a chord member of the energy consumption segment of the truss girder and the web member of the non-energy consumption segment of the truss girder aremade of common steel; and the chord member of the non-energy consumption segment of the truss girder, the frame columns and a node connecting sleeve plate are made of high-strength steel. The frame structure provided by the invention is formed by adoption of high-strength steel and common steel in a combined manner, not only keeps excellent energy consumption performance of common steel, but alsoexerts the advantages of high strength and material saving of high-strength steel, the self weight of the structure is effectively reduced and the earthquake action is reduced.

Description

technical field [0001] The invention belongs to the field of structural engineering, and in particular relates to a multi-story assembled high-strength steel composite steel frame structure with replaceable fasting energy-consuming sections. Background technique [0002] Prefabricated steel structures can realize industrial production, effectively speed up construction progress, reduce labor intensity, and reduce construction pollution, which is the development trend of future construction at home and abroad. Prefabricated steel structures are commonly found in low-rise residential buildings, and the application research in multi-high-rise structures is still in its infancy. At present, truss beams are widely used in multi-story prefabricated steel frame structures. The reason is that truss girders can effectively increase the structural design span, and are convenient for cutting and welding, and are convenient for equipment and pipelines to pass through. They are suitable ...
