Problems solved by technology

[0007] Under the action of external force, earthquake or wind load, the relative rotation angle or displacement between the beam-column joints of the building is small, and the existing dampers installed at the joint positions require a large relative deformation of the structure to fully achieve the energy dissipation effect , so it is often limited in practical applications

Abstract

The invention provides a gear-driven amplified node shear damper, which can amplify the relatively small corner generated at the beam-column node of the assembled building structure under the action of external load as required, and limit the enlarged corner displacement, Give full play to the energy dissipation capacity of the viscoelastic material in the damper to achieve a more ideal energy dissipation effect. That is, when a relative rotation angle occurs at the beam-column joints of the building structure, the rotation angle is amplified by the gear transmission mechanism and transmitted to the turntable. When the turntable rotates, the viscoelastic material is driven to shear hysteretic deformation and consume energy. The magnification of the corner of the invention can be adjusted according to the actual situation of the building structure or the building components, and the installation is simple, and it is a flexible and efficient energy-consuming element.

Description

technical field [0001] The invention provides a gear-driven amplified node shear damper, which is installed at the beam-column node of a prefabricated building structure, and can adjust the smaller relative rotation angle generated at the beam-column node under the action of an external load as required. Amplification, by limiting the enlarged rotation angle, the energy dissipation capacity of the viscoelastic shear material in the damper is fully utilized to consume seismic energy. Background technique [0002] The energy-dissipating and shock-absorbing technology of the structure is to install energy-dissipating devices in some parts of the structure, and dissipate or absorb the energy input into the structure by external force, earthquake action or wind load through the hysteretic deformation of the energy-dissipating device, so as to reduce the The seismic response of the main structure is small, so as to avoid structure damage or collapse, and achieve the purpose of sho...
