Abstract

The invention relates to a U-shaped steel plate damper with corrugations and vertical seams suitable for side columns, which belongs to the field of energy dissipation and shock absorption in civil engineering. The metal damper is composed of two U-shaped energy dissipation parts vertically arranged along the horizontal opening, a corrugated steel plate with vertical seams, an upper cover plate and a lower cover plate. The invention is proposed based on design concepts such as multiple insurance mechanisms, replaceable energy-dissipating components, improved shear bearing capacity, and cooperative work of multiple shear energy-dissipating mechanisms, breaking the limitations of traditional metal dampers. A reasonably designed damper can dissipate energy at the position of the side column; the combination of U-shaped energy-dissipating parts and the twisted vertical seam steel plate forms a multiple insurance mechanism, which improves the problem that the damper is not easy to produce plastic energy consumption during small earthquakes; The position yields, the energy dissipation performance is stable, and the shear bearing capacity is improved. After the earthquake, only the energy consumption parts need to be replaced to restore the function, and the economic benefits are obvious. The metal damper is developing towards the direction of assembly, which is easy to replace, has various layout methods, and the number of energy-consuming parts can be flexibly increased or decreased according to the actual situation.

Description

technical field [0001] This patent relates to a U-shaped steel plate damper with corrugated folded vertical seams suitable for side columns, 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more and more concentrated, resulting in more and more high-rise buildings, the traditional anti-seismic strategy is no longer applicable, and the research of new energy dissipation dampers is imperative.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 trad...
