Abstract

The invention provides a multi-purpose assembled type damper. Two adjacent assembled hexagonal cylinder dampers are connected through damper assembly bolts, a hexagonal soft steel cylinder of each internally assembled hexagonal cylinder damper has six side faces, and the six side faces are connected with the adjacent assembled hexagonal cylinder dampers correspondingly; and the assembled damper types mainly include herringbone dampers and cruciform dampers of the multi-purpose assembled type damper. The multi-purpose assembled type damper has the effects and the advantages that the multi-purpose assembled type damper has large initial stiffness, can make full use of energy dissipation performance of soft steel and lead, has no obvious stress concentration phenomenon, large steel yield area, and good energy dissipation effect, meanwhile, the multi-purpose assembled type damper is easy to manufacture and install and convenient to use, can be used for seismic design of new construction projects, and also be used for reinforcement and maintenance of existing projects.

Description

technical field [0001] The invention relates to a vibration control device for a building structure, in particular to a multipurpose assembled 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 the elastic-plastic hysteretic deformation energy dissipation of some metals is used, 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 structural vibration through the yield hysteresis energy dissipation of the metal, so as to achieve the purpose of reducing the structural response. [0003] The mild steel damper is to make full use of the good hysteresis characteristics of mild steel after entering the plastic stage. In 1972, American scholars such as Kelly and Skinner first began to s...
