The damper comprises connection plates, connection plate threaded holes, fixing end plates, a tension-compression energy-dissipation steel plate, connection energy-dissipation steel plates, squeezing energy-dissipation plates, arc-shaped energy-dissipation steel plates, mild steel energy-dissipation internal cylinders, lead dot holes, an energy-dissipation filling material, energy-dissipation ribs, built-in elliptical holes, end plates, lead dots, a cover plate, tension-compression connectors, coordinated connection rebars and locking nuts. The internal and external multiple energy-dissipation tension-compression damper has the advantages that the initial stiffness is high, the steel yielding area is large, the energy-dissipation effect is good, the structural design of internal and external combined energy dissipationis adopted, multiple energy-dissipation effects are achieved, and energy is more sufficiently dissipated; moreover, the internal and external multiple energy-dissipation tension-compression damper has a reasonable initial stiffness, and can meet the requirements for supporting and bearing of the damper while shock absorption and energy dissipation are achieved.

Description

technical field [0001] The invention belongs to the field of vibration control of building structures, in particular to an internal and external multiple energy-consuming tension-compression 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 some metals have elastic-plastic hysteretic deformation energy dissipation, 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 structure vibration through the yield hysteresis energy consumption of the metal, so as to reduce the structural response. The mild steel damper is to make full use of the soft steel after entering the plastic stage Good hysteresis characteristics. In 1972, American scholars such as Kelly and Skinner first began to s...

Problems solved by technology

[0003] Because the external energy transmitted to the building structure due to earthquakes and other reasons is the root cause of the vibration of the structure, the energy dissipation properties of the damper will be the key to reducing the vibration response of the structure. The dampers currently researched and developed are prone to insufficient energy dissipation characteristics and The uncoordinated structure loses the restraint and anti-buckling effects, resulting in a significant reduction in its energy dissipation capacity
