According to the energy dissipation beam embedded with viscoelastic layers, the damping device is embedded in the concrete beam, so that the energy dissipation beam is formed, and the concrete beam constrains the deformation outside the internal damping device surface, so that it is ensured that the stable deformation and energy consumption work of the damping device in the established axis direction is carried out.

Description

technical field [0001] The invention relates to the technical field of vibration control of building structures, in particular to an energy-dissipating beam embedded with a viscoelastic layer. Background technique [0002] The application of energy dissipation and shock absorption technology in building structures against earthquakes and high-rise wind vibrations is increasing. The main principle is to transfer the energy introduced into the building structure through these energy dissipation and shock absorbing devices Dissipated in the form of deformation, friction, etc., the vibration response of the structure is slowed down under the action of large dynamic loads, and the structure is prevented from being damaged. As a non-load-bearing additional component of the structure, the damper can increase the structural rigidity, increase the structural damping, and improve the structure. vibration characteristics. [0003] At present, most dampers and energy dissipators design...

AI Technical Summary

Problems solved by technology

[0003] At present, most dampers and energy dissipators designed and researched on energy dissipation and shock absorption are based on in-plane stress and deformation, ignoring out-of-plane deformation. The connection of the part often causes the energy dissipator to fail or fail to play the role of energy dissipation due to the force or deformation outside the plane. This is a key technical problem that needs to be solved for the energy dissipation and shock absorption device
