Second-order enhanced coupling beam type metal damping shock absorption system

Abstract

The invention discloses a second-order enhanced coupling beam type metal damping shock absorption system. The second-order enhanced coupling beam type metal damping shock absorption system comprises a plurality of coupling beam soft steel dampers, the plurality of coupling beam soft steel dampers are distributed in a plurality of floors, and at least one coupling beam soft steel damper is arranged in each floor; each coupling beam soft steel damper comprises a first connecting plate and a second connecting plate, a first energy dissipation mechanism and a second energy dissipation mechanism are arranged between the first connecting plate and the second connecting plate, and the first energy dissipation mechanism comprises a first U-shaped energy dissipation plate and a second U-shaped energy dissipation plate; the second energy dissipation mechanism comprises a rectangular energy dissipation plate assembly; the first U-shaped energy dissipation plate and the second U-shaped energy dissipation plate are arranged on the two sides of the rectangular energy dissipation plate assembly; and the rectangular energy dissipation plate assembly is connected with the first connecting plate through a sliding support assembly. After the damping system is installed, the rigidity of lost parts of a building can be sequentially enhanced, the situation that the damage to the connecting beam damper part in a certain area is too large, and consequently an anti-seismic defense line is lost is avoided, and the overall structure is more convenient to replace and maintain.

Description

technical field

[0001] The invention relates to the anti-seismic field of civil engineering, in particular to a second-order reinforced coupling beam metal damping system. Background technique

[0002] Shear walls have the advantages of good structural integrity, no column corners for residential buildings, and convenient room settings. Therefore, they are widely used in building structures. However, under the action of strong earthquakes, the bottom of the wall and the middle of the coupling beam of the shear wall structure are severely damaged. If the coupling beam is the first line of anti-seismic defense, if the deformation is too large, it will be difficult to repair it after the earthquake. Under the earthquake action of the shear wall structure, the connecting beam or the connecting beam with conventional dampers is used as the first line of defense. If damage occurs, the deformation will further accumulate in the height area of ​​the damaged part, forming a weak part...
