The olive-shaped quadruple energy-consuming type damper has the beneficial effects that the initial stiffness is large, the material yield dispersion area is large, and the damper is designed by adopting the quadruple energy-consuming structure, cab increase the integral stiffness of the building structure when being used normally, and can decrease the earthquake reaction of the building structure when an earthquake happens.

Description

technical field [0001] The invention belongs to the field of vibration control of building structures, in particular to an olive-shaped quadruple energy-dissipating 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 this prope...

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
