Abstract

The invention provides a connection type tension and compression damper internally provided with an energy dissipation disc, and belongs to the field of architectural structure vibration control. Theconnection type tension and compression damper internally provided with the energy dissipation disc comprises tension and compression energy dissipation steel plates, energy dissipation ribs, internally arranged round holes, extrusion friction energy dissipation plates, connection plates, connection plate screw holes, lead dot holes, tension and compression energy dissipation discs and lead dots.The connection type tension and compression damper internally provided with the energy dissipation disc has the beneficial effects that initial rigidity is high, yield area of steel materials is large, the energy dissipation effect is excellent, and transmission type multiple energy dissipation effect is achieved; after an earthquake, the extension and compression discs can be replaced, the maintenance cost is low, and material waste is not liable to occur; energy dissipation of the damper is fuller by the energy dissipation ribs and the internally arranged round holes; during tension and compression, friction energy dissipation is achieved through adopting the tension and compression energy dissipation steel plates and the extrusion friction energy dissipation plates, and therefore damping is generated and energy is dissipated; and friction damping, energy dissipation effect and energy dissipation magnification between the tension and compression energy dissipation steel plates and the extrusion friction energy dissipation plates can be adjusted by adjusting the lead dots based on actual requirements of a building structure, and therefore generated damping force changes as well.

Description

technical field [0001] The invention belongs to the field of vibration control of building structures, in particular to a tension-compression damper with built-in energy-dissipating disk connections. 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 ...

Problems solved by technology

[0003] However, 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 It can only 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
