Abstract

The invention discloses an intelligent regulating double-control composite damping component, and belongs to the technical field of engineering structure earthquake resistance and energy-dissipating earthquake reduction. The intelligent regulating double-control composite damping component comprises a steel frame and further comprises an intelligent identification device and an intelligent regulating device which are distributed on the steel frame, wherein the periphery of the steel frame is constituted by I-shaped steel, and a small-displacement energy-dissipating device and a large-displacement energy-dissipating device are arranged in the middle of the steel frame to constitute two sets of earthquake reduction devices; and the intelligent identification device and the intelligent regulating device are mounted on the steel frame, and the middle of the steel frame is constituted by the small-displacement energy-dissipating device and the large-displacement energy-dissipating device which are mutually superposed through a bearing to form a whole. The problem that traditional dampers cannot balance different energy-dissipating demands of the small displacement and the large displacement is solved, the high efficiency of the disc viscoelastic dampers and the economical efficiency of the metal dampers are sufficiently utilized, wind vibration and earthquake responses of a buildingstructure are reduced jointly, the wind vibration and earthquake resistance of a building is improved, and the advantages that safety, reliability and the high efficiency are achieved, and the vibration responses of the structure are reduced better are achieved.

Description

technical field [0001] The invention relates to a damper, in particular to an intelligent mediation dual-control composite damping member, which belongs to the technical field of energy dissipation and shock absorption. Background technique [0002] Both viscoelastic and metallic dampers are the most commonly used dampers in civil engineering. The viscoelastic damper is a damper suitable for small displacements. It can start to dissipate energy under small displacements, and has good fatigue performance and energy dissipation performance. However, under the action of moderate or large earthquakes, the vibration displacement of the building is large. , the vibration frequency is reduced, so that the viscoelastic part will be damaged prematurely under the action of moderate or large earthquakes. The metal damper is a kind of damper suitable for resisting moderate or large earthquakes. Under large displacements, it can dissipate the seismic energy through the yielding of mild ...
