Abstract

The invention provides a multi-energy-consumption steel plate connection transmission type damper, and belongs to the field of vibration control of building structures. The multi-energy-consumption steel plate connection transmission type damper comprises transmission energy consumption steel plates, an energy consumption rib, an internal elliptical hole, a viscoelastic friction energy consumptionbacking plate, a connecting plate, a connecting plate screw hole, a lead dot hole, a tension-compression connection energy consumption steel plate, a lead dot and an energy consumption connection soft steel plate. The multi-energy-consumption steel plate connection transmission type damper has the beneficial effects that the lead dot is used for connecting the transmission energy consumption steel plate and the tension-compression connection energy consumption steel plate, and the lead pin and the energy consumption connection soft steel plate are used for connecting the two transmission energy consumption steel plates, the tension-compression connection energy consumption steel plate drives the transmission energy consumption steel plates to deform and consume energy during tension and compression, and the transmission energy consumption steel plates drive the energy consumption connection soft steel plate to deform and consume energy, so that the transmission type multi-fold energyconsumption effect of the energy consumption steel plate is realized, the damper has a better tension-compression energy consumption effect and the damper consumes more energy, the arranged lead dot has a good energy-dissipating effect and can adjust the damping energy consumption effect and energy consumption amplification factor according to the actual situation of the building structures, and the seismic response of the building structures is reduced.

Description

technical field [0001] The invention belongs to the field of vibration control of building structures, in particular to a multi-energy-dissipating steel plate connection transfer type 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 th...

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
