Spindly tension-compression type energy-dissipating damper

Abstract

The invention belongs to the field of vibration control of a building structure, in particular to a spindly tension-compression type energy-dissipating damper. The damper comprises an upper plate, a lower plate, a screw hole A, a screw hole B, an external curved energy-dissipating steel plate, a spindly energy-dissipating steel plate, elliptical holes, a coordinated connection steel bar, an energydissipation rib, internal curved energy-dissipating steel plates, a spindly foaming aluminum energy absorbing plate, elastic bonding filling material and lock nuts. The damper is enclosed by the upper plate, the lower plate, the external curved energy-dissipating steel plate and the spindly foaming aluminum energy absorbing plate. The elliptical holes are arranged in the spindly energy-dissipating steel plate. The spindly foaming aluminum energy absorbing plate is arranged at the position, close to the spindly energy-dissipating steel plate internally equipped with the elliptical holes, the interior of the enclosed structure. The structure enclosed by the upper plate, the lower plate, the external curved energy-dissipating steel plate and the spindly foaming aluminum energy absorbing plate is filled with the elastic bonding filling material. When the damper is used in a normal state, the overall rigidity of a building structure is enhanced. In case of an earthquake, earthquake reactions of the building structure are reduced.

Description

technical field [0001] The invention belongs to the field of vibration control of building structures, in particular to a spindle-shaped tension-compression energy dissipation damper. Background technique [0002] Metallic yielding dampers are various forms of damping energy dissipators made of mild steel or other soft metal materials. Metals have good hysteretic properties after yielding, and some metals have elastic-plastic hysteretic deformation energy dissipation, including mild steel dampers, lead dampers, and shape memory alloys (SMA) dampers. The mechanism of its vibration control on the structure is to dissipate part of the energy of the structure vibration through the yield hysteresis energy consumption of the metal, so as to reduce the structural response. The mild steel damper is to make full use of the soft steel after entering the plastic stage Good hysteresis characteristics. In 1972, American scholars such as Kelly and Skinner first began to study the use of...

Problems solved by technology

At present, the initial stiffness of many dampers is not large enough, the yield dispersion area of ​​the material is not large enough, and the design of the energy dissipation structure is not very sufficient, so that the energy such as kinetic energy or elastic potential energy of the structure cannot be fully converted into heat energy and dissipated. Many dampers are only It can increase the overall stiffness of the building structure during normal use, but when a large earthquake occurs, many dampers cannot meet the requirements of reducing the seismic response of the building structure
