The invention discloses a steel lead lamination shearing damper which comprises a damper steel end plate, an energy consumption soft steel plate, an energy consumption lead plate blocking plate, a damper fixing plate and an energy consumption lead plate. The energy consumption soft steel plate and the energy consumption lead plate are arranged in a lamination mode to form an energy consumption part. The energy consumption lead plate blocking plate is arranged on the outside of the energy consumption lead plate. The energy consumption part is fixedly connected with the damper steel end plate fixedly connected with the damper fixing plate, one end of the damper fixing plate is connected with a steel I beam, and the other end of the damper fixing plate is connected with the top of a herringbone support. The damper is high in initial rigidity and high in material yield dispersion area. No obvious stress concentration exists. The soft steel and the lead have good coordination performance, the material utilization rate is high, and the energy consumption effect is good. Meanwhile, the damper is simple in manufacture and installation, convenient to use, capable of being used for seismic design of newly-built projects and also capable of being used for reinforcement and maintenance of the existing projects.
Description
technical field [0001] The invention relates to a vibration control device for a building structure, in particular to a steel-lead laminated shear damper for building structure vibration control. 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 schol...
