U-shaped belt corrugated vertical-slit steel plate damper suitable for side column

Abstract

The invention relates to a U-shaped belt corrugated vertical-slit steel plate damper suitable for a side column, and belongs to the field of civil engineering energy dissipation and shock absorption.The metal damper is composed of two U-shaped energy dissipation parts vertically arranged along a horizontal opening, corrugated vertical-slit steel plates, an upper cover plate and a lower cover plate. The damper is provided on the basis of the design concepts that multiple safety mechanisms are adopted, energy dissipation parts can be replaced, the shear bearing capacity is improved, and multiple shear energy dissipation mechanisms work cooperatively, and the limitation of a traditional metal damper is broken through. The reasonably designed damper can dissipate energy at the position of theside column. The U-shaped energy dissipation parts and the corrugated vertical-slit steel plates are combined to form a multi-safety mechanism, and the problem that the damper is not prone to generating plastic energy dissipation during a small earthquake is solved. The slit steel plates yield at multiple positions, the energy dissipation performance is stable, the shear bearing capacity is improved, only energy dissipation parts need to be replaced after an earthquake to recover the function, and the economic benefits are obvious. The metal damper develops towards the assembling direction, replacement is easy and convenient, arrangement modes are various, and the number of energy dissipation parts can be flexibly increased or decreased according to actual conditions.

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...
