Abstract

The invention discloses a self-resetting composite structure beam-column joint and a construction method thereof.The self-resetting composite structure beam-column joint comprises an I-shaped steel beam, T-shaped connecting pieces, friction components, a square steel tube concrete column and SMA screws, the I-shaped steel beam is horizontally arranged on the side edge of the square steel tube concrete column, and the T-shaped connecting pieces are symmetrically arranged on the outer side of the beam end of the I-shaped steel beam up and down; one end of the T-shaped connecting piece is fixed with a flange plate of the I-shaped steel beam through a third connecting bolt, and the other end of the T-shaped connecting piece is connected with the square steel tube concrete column through an SMA screw rod; the friction components are symmetrically arranged on the two sides of a web of the I-shaped steel beam, one end of each friction component is fixed to the side wall of the square steel tube concrete column through a first connecting bolt, and the other end of each friction component is connected with the web of the I-shaped steel beam through a second connecting bolt. According to the invention, the self-resetting capability is provided for the joint through the superelasticity of the SMA screw rod; friction components are used for providing good energy dissipation capacity, site welding is not needed in the joint assembly construction process, and the requirements for industrialization and assembly of a composite structure building are met.

Description

technical field [0001] The invention belongs to the field of anti-seismic and shock-absorbing technology of structural engineering, and in particular relates to a beam-column node of a self-resetting composite structure and a construction method thereof. Background technique [0002] At present, the anti-seismic theory of structures is becoming more and more perfect, but earthquakes still seriously threaten the survival and development of human society; although the building structures designed according to the existing Unrecoverable residual deformation may be generated when the earthquake action is higher than the seismic fortification intensity of the area; the residual deformation not only affects the ability of the structure to withstand aftershocks, but also the damage caused by excessive plastic deformation and the residual deformation that is difficult to recover have to be recovered after the earthquake. It will be dismantled later, even if it is managed to repair, ...
