Steel lead laminated porous energy dissipation board

Abstract

The invention discloses a steel and lead lamination porous energy consumption plate which comprises energy consumption steel plates, energy consumption lead plates and a fixing part. According to the steel and lead lamination porous energy consumption plate, an energy consumption part is formed by the energy consumption steel plates and the energy consumption lead plates in an alternative lamination mode. The energy consumption part is one part of an eccentric ring, and a plurality of internally-formed holes are formed in the energy consumption part. The fixing part comprises the flat and straight energy-consumption steel plates and the energy consumption lead plates. The fixing part is tangent with the energy consumption part, and the fixing part is covered by the energy consumption steel plates and the energy consumption lead plates. The steel and lead lamination porous energy consumption plate has the advantages that the initial stiffness is large, the material yielding and scattering area is large, the obvious stress concentration phenomenon does not exist, soft steel and lead have good harmony, the material utilization effect is high, the energy consumption effect is good, meanwhile, the steel and lead lamination porous energy consumption plate is easy to manufacture and install, convenient to use and capable of being used for the seismic design of new building engineering and suitable for strengthening and maintaining existing engineering.

Description

technical field [0001] The invention relates to a building structure vibration control device, in particular to a steel-lead laminated porous energy-dissipating plate 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 certain metals is used, including mild steel dampers, lead dampers, and shape memory alloy (shapememoryalloys, 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 plasti...
