Description
Technical Field
The invention relates to a vibration control device for a building structure, in particular to a multipurpose assembled damper.
Background
The metallic yielding damper (metallic yielding damper) is a form of damping energy consumer made of mild steel or other soft metallic material. The metal has good hysteresis performance after yielding, and the elastoplastic hysteresis deformation energy consumption of certain metals is utilized, including soft steel dampers, lead dampers, shape memory alloy (shape memory alloys, SMA for short) dampers and the like. The mechanism for controlling the vibration of the structure is to dissipate part of energy of the vibration of the structure through the yield hysteresis energy consumption of the metal, so that the aim of reducing the structural reaction is fulfilled.
The soft steel damper fully utilizes the good hysteresis characteristic of soft steel after entering a plastic stage. In 1972, american students, such as Kelly and skenner, began to study the dynamic response of structures using this property of mild steel, and proposed several forms of mild steel dampers, including torsion beams, bending beams, U-bar energy dissipaters, and the like. Subsequently, other scholars have successively proposed various forms of mild steel dampers, such as X-shaped, triangular plate mild steel dampers, E-shaped steel dampers, C-shaped steel dampers, for example. Theoretical analysis and experimental research by a plurality of scholars at home and abroad prove that the soft steel damper has the characteristics of stable hysteresis characteristic, good low cycle fatigue performance, long-term reliability, no influence of environment and temperature and the like, and is a promising energy consumer.
The lead damper fully utilizes the characteristics of high density, low melting point, high plasticity, low strength, strong corrosion resistance, strong lubricating capability and the like, and simultaneously can absorb a large amount of energy in the deformation process due to higher ductility and flexibility, has stronger deformation tracking capability, and can recover the structure and performance to the state before deformation through dynamic recovery and recrystallization processes, so the lead damper has the advantages of unlimited service life, reliable damping, sensitivity to displacement change, simple structure, no maintenance in work and the like. But it has the disadvantages of poor recovery, lead contamination, etc.
