Problems solved by technology

[0005] However, the relative rotation angle or displacement between the beam-column joints of the building under the action of external force, earthquake or wind load 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. performance, so it is often limited in practical applications

Embodiment Construction

[0029] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and technical solutions.

[0030] A fan-shaped support rotary amplified node shear damper, comprising a side plate 1, a bottom plate 2, a rotating shaft 3, a fan-shaped support plate 4, a rotating plate 5, a rounded rectangular chute 6, a bolt 7 and a viscoelastic gasket 8;

[0031] The side plate 1 and the bottom plate 2 are hinged through the rotating shaft 3 to form a rotatable mechanism;

[0032] The fan-shaped support plate 4 is divided into an inner fan-shaped support plate and an outer fan-shaped support plate, both of which take the rotating shaft 3 as the center of the circle, and are respectively vertically fixed on the centerlines of the side plate 1 and the bottom plate 2; the inner fan-shaped support plate and the outer fan-shaped support plate The support plates are coplanar, and there is a gap between them; the two inner fan-shaped...

Abstract

The invention provides a fan-shaped support rotary amplifying node shear damper, which belongs to the technical field of civil engineering. The relatively small displacement of the building structure at the beam-column joint or between the structural layers under the action of external load is amplified as needed, and by limiting the amplified displacement, the energy dissipation characteristics of the viscoelastic material in the damper can be fully utilized to achieve a more ideal energy consumption effect. That is, when the building structure drives the side plate to rotate, the fan-shaped support plate rotates relative to it. Under the drive of the bolt, the rotating plate rotates, which in turn drives the viscoelastic gasket to produce shear 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 building components, the installation is simple, and it is a flexible and efficient energy-consuming element.

Description

technical field [0001] The invention relates to a fan-shaped support rotary amplifying node shear damper, which can amplify the relatively small displacements generated at the beam-column nodes or between the structural layers of the building structure under the action of external loads as required, and limit the displacement after the amplification. , give full play to the energy dissipation characteristics of the viscoelastic material in the damper, and achieve a more ideal energy dissipation effect. The invention is suitable for vibration reduction control of engineering structures and belongs to the technical field of civil engineering. Background technique [0002] The building structure will respond when it is disturbed or stimulated by the outside world, because the excitation makes the system obtain energy input. At the same time, the system can convert the input energy into heat energy or other forms of energy through a certain mechanism and consume it, so that the...
