The invention discloses a metal viscoelastic composite wind-resistant shock-absorbing multistage yield damper, and relates to the technical field of earthquake prevention and disaster reduction, the metal viscoelastic composite wind-resistant shock-absorbing multistage yield damper comprises an upper connecting part, a lower connecting part and energy consumption pin shafts, the upper connecting part comprises an upper connecting plate and a middle plate, and the middle plate is provided with a plurality of columns of middle plate energy consumption pin shaft holes; the apertures of the multiple rows of middle plate energy consumption pin shaft holes are gradually increased; the lower connecting part comprises a lower connecting plate and two outer side plates, the two outer side plates are arranged on the two sides of the middle plate, a viscoelastic layer plate is arranged between the two outer side plates and the middle plate, and outer side plate energy dissipation pin shaft holes concentric with the middle plate energy dissipation pin shaft holes are formed in the two outer side plates; the energy consumption pin shaft penetrates through the middle plate energy consumption pin shaft hole and the outer side plate energy consumption pin shaft hole to connect the middle plate, the outer side plate and the viscoelastic layer plate in a fastening manner; the two ends of the energy consumption pin shaft extend towards the outer side of the outer side plate and are sleeved with pre-pressing springs. The device is simple in structure, the specified energy dissipation component can deform and dissipate energy to yield under small, medium and large earthquakes, and multi-stage energy dissipation is achieved.
本发明公开了一种金属粘弹性复合型抗风减震多级屈服阻尼器，涉及防震减灾技术领域，包括：上连接部、下连接部和耗能销轴，上连接部包括上连接板和中间板，中间板上开设有多列中间板耗能销轴孔，多列中间板耗能销轴孔的孔径逐渐增大；下连接部包括下连接板和两块外侧板，两块外侧板布置在中间板的两侧，两块外侧板和中间板之间设有粘弹性层板，两块外侧板上开设有与中间板耗能销轴孔同心的外侧板耗能销轴孔；耗能销轴穿过中间板耗能销轴孔和外侧板耗能销轴孔，将中间板、外侧板和粘弹性层板紧固连接；耗能销轴的两端向外侧板的外侧延伸，且套设有预压弹簧。本发明构造简单，能在小中大震下使指定的耗能部件变形耗能至屈服，即实现多级耗能。
