Self-resetting support

Abstract

The invention relates to the field of engineering structure shock isolation and absorption, and discloses a self-resetting support. The self-resetting support comprises an upper support plate and a lower support plate and further comprises a supporting piece and energy dissipaters, the supporting piece is placed on the lower support plate, the upper support plate is placed on the supporting piece,the plurality of energy dissipaters are arranged on the periphery of the supporting piece, and the two ends of each energy dissipater are detachably connected with the upper support plate and the lower support plate correspondingly. According to the self-resetting support provided by the invention, swing deformation occurs under the action of an earthquake, the earthquake energy can be dissipatedthrough the energy dissipaters in the support, the vibration frequency of the structure can be changed through swing of the supporting piece in the support, and meanwhile, the support has good self-resetting capacity under the self-weight of the upper structure, so that the problem that a support in an existing engineering structure is sheared and damaged in a strong earthquake is solved, the energy dissipation capacity and the self-resetting capacity of the support are enhanced at the same time, and the post-earthquake function restorability of the whole engineering structure is improved.

Description

technical field [0001] The invention relates to the field of seismic isolation and shock absorption of engineering structures, in particular to a self-resetting support. Background technique [0002] Earthquake is a common natural disaster. Once an engineering structure is damaged by an earthquake, it will cause huge casualties and economic losses, and it is extremely difficult to repair after the earthquake. Therefore, it is of great significance to improve the seismic performance of engineering structures, especially the recoverability after earthquakes. [0003] In engineering structures, especially bridge structures, it is usually necessary to install bearings between the superstructure and the substructure to resist external loads, temperature changes, earthquakes, etc. Traditional bearings such as plate rubber bearings adapt to the structural deformation under earthquake action through the shear deformation between the laminated rubber steel plates, but due to the lim...
