Cantilever truss with viscous damper wall
The invention discloses an outrigger truss with a viscous damper wall, and relates to the technical field of buildings, the viscous damping wall is arranged at the end part of a rigid outrigger truss, and the outrigger truss deforms under the action of an earthquake to drive a steel plate in a damper to reciprocate in high-viscosity viscous liquid, so that the damping liquid generates shear deformation to generate viscous damping force; and the earthquake energy is dissipated. The damping force of the viscous damper in the outrigger truss is greatly increased, the energy consumption efficiency of the damping wall is fully exerted, the additional damping ratio of the structure under the earthquake action is increased, and a better damping effect can be achieved. In a rare earthquake, the viscous damping wall can avoid out-of-plane instability and ensure that the viscous damping wall plays a role, and can be repeatedly used under the earthquake and heavy wind load. And meanwhile, stress concentration generated by a traditional outrigger truss in the core tube wall can be avoided, and the core tube shear wall is prevented from being seriously damaged.
本发明公开了一种带有粘滞阻尼器墙的伸臂桁架，涉及建筑技术领域，在刚性伸臂桁架端部布置粘滞阻尼墙，由伸臂桁架在地震作用下的变形带动阻尼器内部钢板在高粘度粘滞液体中往复运动，使阻尼液产生剪切变形而产生黏滞阻尼力，并耗散地震能量。将伸臂桁架中粘滞阻尼器的阻尼力大幅增加，充分发挥阻尼墙的耗能效率，提高地震作用下结构的附加阻尼比，能够取得更好的减震效果。粘滞阻尼墙在罕遇地震下，可以避免面外失稳，确保发挥作用，可在地震和大风荷载下重复使用。同时它也可以避免传统伸臂桁架在核心筒墙中产生的应力集中，避免核心筒剪力墙发生严重破坏。
