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 implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0030] A fan-shaped support rotation amplified nodal 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, bolts 7 and a viscoelastic gasket 8;

[0031] The side plate 1 and the bottom plate 2 are hinged by a 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 a 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; two inner fan-shap...

Abstract

The invention provides a fan-shaped supporting rotating amplifying type joint shearing damper and belongs to the technical field of civil engineering. Relatively small displacement produced at a beam-column joint or between structure layers of a building structure under the effect of an outer load is amplified according to the requirement, by limiting the amplified displacement, the energy consumption characteristic of a viscoelastic material in the damper is given to full play, and the more ideal energy consumption effect is achieved. When the building structure drives a side plate to rotate, accordingly fan-shaped supporting plates rotate relatively, under driving of bolts, a rotating plate rotates, and then a viscoelastic gasket is driven to produce shear deformation to consume energy. The amplification times of the rotating angle can be adjusted according to the actual situation of the building structure or a building member, mounting is easy, and the fan-shaped supporting rotating amplifying type joint shearing damper is a flexible and efficient energy consumption element.

Description

technical field [0001] The invention relates to a fan-shaped support rotation amplifying node shear damper, which can amplify the relatively small displacement generated at the beam-column node or between the structural layers of the building structure under the action of external load as required, and limit the amplified displacement , 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] A 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 energy forms through a certain mechanism and consume it, so that the input energy and the...
