A detachable U-shaped corrugated belt double-layer steel plate damper with oblique seams

Abstract

The invention relates to a detachable U-shaped corrugated belt double-layer steel plate damper with oblique seams, which belongs to the technical field of energy dissipation and shock absorption in civil engineering. The metal damper is composed of several U-shaped energy-consuming parts, an upper cover plate and a lower cover plate of double-layer steel plates with oblique seams. The present invention breaks the limitations of traditional metal dampers based on design concepts such as multi-directional energy dissipation, detachable energy dissipation elements, improved shear bearing capacity, restraint of out-of-plane buckling, cooperative work of various shear energy dissipation mechanisms, and double insurance mechanisms. . The U-shaped energy dissipation units are connected in parallel, which effectively realizes the multi-directional energy dissipation of the damper; through reasonable design, the damper can achieve multi-position yielding, the energy dissipation performance is stable, and the shear bearing capacity is greatly improved; U-shaped energy dissipation parts and double-layer The steel plates with inclined seams consume energy together, forming a double insurance mechanism; after the earthquake, only the energy-consuming parts need to be replaced to restore the normal function. The metal damper is developing towards the direction of assembly, which is easy to replace, has obvious economic benefits, and can be effectively combined with the support to provide lateral force for the support.

Description

technical field [0001] This patent relates to a detachable U-shaped corrugated belt double-layer steel plate damper with oblique seams, which can be used to control the seismic response of the structure, thereby improving the seismic performance of the main structure, and belongs to the technical field of energy dissipation and shock absorption in civil engineering. Background technique [0002] Earthquake is a natural disaster, which is sudden and destructive. The occurrence of strong earthquakes may cause huge economic losses and casualties. my country is an earthquake-prone country, and most of the first-tier cities are in the earthquake zone. With the acceleration of the development of our country, the urban population and facilities are becoming more and more concentrated, resulting in more and more high-rise buildings, the traditional anti-seismic strategy is no longer applicable, and the research of new energy dissipation dampers is imperative. [0003] The tradition...
