Problems solved by technology

[0003] The shear wall structure has strong anti-sway stiffness, so the displacement of the structure is small under the action of earthquake and wind load, but the damper can only exert a good energy dissipation effect under large displacement, so the shear wall , frame tube and other structures, can not achieve satisfactory results

Abstract

The invention relates to a horizontal displacement amplification device. The horizontal displacement amplification device comprises a box girder section, a gear set, a gear shaft, a hinged shaft support, a high-strength bolt, an upper rack plate, a lower rack plate and a shearing type damper. The structure horizontal displacement is amplified by multiple times through the gear set to be transmitted to the damper, the shearing type damper can bring a very good energy dissipation damping effect into play, and the horizontal displacement amplification device is suitable for the anti-seismic design of structures, such as a shearing wall and a frame cylinder, with small structural interlayer displacement. For the purpose of increasing the application range, the shearing type damper can be designed and used for a small earthquake or wind vibration, and the box girder section is designed into two-section energy dissipation and used for resisting an earthquake which rarely occurs.

Description

technical field [0001] The invention belongs to the anti-seismic field of building structures, and in particular relates to a horizontal displacement amplification device. Background technique [0002] In recent years, with the rapid development of high-rise buildings, issues such as seismic vibration and wind-induced vibration have received extensive attention and research. Passive control technologies such as energy dissipation and shock absorption are widely used to reduce the vibration response of high-rise buildings under the action of earthquake and wind; the shear type damper is a device that uses shear deformation to dissipate energy, and the common ones are: shear type Metal dampers, viscous dampers, etc., are displacement-dependent dampers that are mainly used to reduce seismic response. [0003] The shear wall structure has strong anti-sway stiffness, so the displacement of the structure is very small under the action of earthquake and wind load, but the damper c...
