Problems solved by technology

[0002] In recent years, the self-resetting structure, which aims to reduce the residual deformation of the building structure after the earthquake and effectively controls the maximum deformation of the structure, has gradually become a research hotspot at home and abroad. Plastic deformation makes structural maintenance difficult, and some structures cannot even be completely repaired and cannot continue to be used

Abstract

The invention discloses an anti-seismic toughness steel pipe concrete column and shape steel concrete beam frame and a construction method thereof. A frame structure is constructed on the basis of concrete and comprises a steel pipe concrete column, angle steel supports, connecting screw rods, a limiting component, anchor rods, a shape steel concrete beam, a beam end part overhanging pre-buried steel beam, pull rods and energy dissipation components. A plurality of butterfly spring groups are arranged in the middle of the beam end part overhanging pre-buried steel beam side by side, the pull rods are connected with beam column joints, the energy dissipation components are arranged on an upper flange and a lower flange of the beam end part overhanging pre-buried steel beam, the bottom of the column is placed in a groove of a concrete foundation, the lower ends of the anchor rods are anchored in the concrete foundation and penetrate through the angle steel supports and a limiting device,and the butterfly spring groups are installed at the top ends of the anchor rods on the upper portions of the angle steel supports. By means of the frame, a beam column can be kept elastic under thestrong earthquake action, the residual deformation of the structure under the earthquake action can be effectively reduced, and the replaceability of the external energy dissipation and self-reset components is realized.

Description

technical field [0001] The invention relates to the technical field of anti-seismic structure systems, and more specifically relates to a frame composed of prefabricated anti-seismic ductile concrete-filled steel pipe columns and steel concrete beams and a construction method thereof. Background technique [0002] In recent years, the self-resetting structure, which aims to reduce the residual deformation of the building structure after the earthquake and effectively controls the maximum deformation of the structure, has gradually become a research hotspot at home and abroad. Plastic deformation makes structural maintenance difficult, and some structures cannot even be completely repaired and cannot continue to be used. [0003] Therefore, how to provide a self-resetting frame structure with strong earthquake resistance and high structural toughness and its construction method is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004...
