All-steel self-restoring buckling-restrained brace based on disc spring

Abstract

The invention discloses an all-steel self-restoring buckling-restrained brace based on a disc spring, and belongs to the technical field of disaster prevention and shock absorption for civil engineering. The all-steel self-restoring buckling-restrained brace is mainly composed of an in-line steel plate inner core, a stiffening rib, a non-bonding material, an inner sleeve, an outer sleeve, the combined disc spring, a stop block, a stop plate, a left connection plate and a right connection plate. The brace is composed of a buckling-restrained part and a self-restoring part, the buckling-restrained part is composed of the in-line steel plate inner core, the stiffening rib, the non-bonding material, the inner sleeve, the left connection plate and the right connection plate, and the self-restoring part is composed of the inner sleeve, the disc spring, the stop block, the stop plate and the outer sleeve. The buckling-restrained brace disclosed by the invention is capable of effectively solving the problems of the increased post-earthquake maintenance and reconstruction cost due to the excessive residual deformation of the buckling-restrained brace under the action of a major earthquake or a medium earthquake, and high cost, low ultimate elastic deformation capacity and the like of a self-restoring material in an existing self-restoring energy dissipating brace. The all-steel self-restoring buckling-restrained brace based on the disc spring is simple in structure, clear in working mechanism, economic and applicable, and stable in performance.

Description

technical field [0001] The invention relates to the field of anti-seismic technology of civil engineering, and is an energy-dissipating shock-absorbing device applied in the field of construction and bridge engineering. The all-steel self-resetting anti-buckling support has good energy-dissipating capacity and self-resetting function. Background technique [0002] In recent years, the social and economic problems caused by earthquakes have drawn more and more attention to structural anti-seismic technology. The frame bracing system solves the problem of lateral stiffness of the structure to a certain extent, but under the reciprocating load of a large earthquake, the ordinary bracing is likely to cause failure and destruction of itself and the connection. dissipate the seismic input energy. The anti-buckling support can yield without buckling under both tension and compression, so it overcomes the shortcomings of traditional supports that the buckling strength under compres...
