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

Abstract

The invention provides a multi-energy-consumption damper with an energy consumption time sequence. The multi-energy-consumption damper is formed by mechanically connecting outer sleeve profile steel, lining profile steel, a connecting piece and a core tube through high-strength bolts, more energy can be absorbed and dissipated through the performance of the connecting piece and an elastic piece in the core tube, therefore, the damper has the self-resetting capability while having the energy-consuming time sequence property. The invention further provides an optimal design method of the multi-energy-consumption damper with the energy consumption time sequence.

Description

【Technical field】 [0001] The invention relates to the technical field of dampers, in particular to a multiple energy dissipation damper with an energy dissipation sequence and an optimization design method thereof. 【Background technique】 [0002] Metal yield dampers are various forms of damping dissipators made of mild steel or other soft metal materials. Metals have good hysteretic properties after yielding, and utilize the elastic-plastic hysteretic deformation energy dissipation of some metals, including mild steel dampers, lead dampers and shape memory alloy dampers. The mechanism of its vibration control of the structure is to dissipate part of the energy of the structural vibration through the yield hysteretic energy dissipation of the metal, so as to achieve the purpose of reducing the structural response. Good hysteresis characteristics. At present, the initial stiffness of many dampers is not large enough, the material yield dispersion area is not large enough, an...
