Speed type and displacement type damper combined system of longitudinal vibration/earthquake reduction of large-span bridge
The invention provides a speed type and displacement type damper combined system of longitudinal vibration/earthquake reduction of a large-span bridge. The combined system adopts a viscous damper to work in medium and small earthquakes, and adopts a soft steel damper to work in large earthquakes. In addition, the invention further provides a method for switching from viscous steel to soft steel. Therefore, full-time damping energy dissipation of an earthquake reduction system under different earthquake magnitudes can be solved. In order to achieve the purpose, the technical scheme adopted by the invention is characterized in that the speed type and displacement type damper combined system of longitudinal earthquake reduction of the bridge comprises a viscous damper and a soft steel damper;a rigid support seat is included, a viscous damper cylinder barrel is connected with a first bridge structure, a piston rod is connected with the rigid support seat, the cylinder barrel is further connected with the soft steel damper, and the rigid support seat and the soft steel damper are connected with a second bridge structure; and a switching device is also included and is used for switchinga connection state of ''the piston rod and the rigid support seat'' into the connection state of the ''cylinder barrel and the soft steel damper''.
本发明提供一种大跨度桥梁纵向减振/震的速度型与位移型阻尼器组合系统。该组合系统在中小地震时采用粘滞阻尼器工作，在大地震时采用软钢阻尼器工作。并且，本发明还提供了由粘滞切换为软钢的方法。因而，本发明得以解决在不同震级下减震系统的全时阻尼耗能。为了实现上述目的，本发明采用的技术方案为：一种桥梁纵向减震的速度型与位移型阻尼器组合系统，包括粘滞阻尼器与软钢阻尼器；还包括刚性支座，粘滞阻尼器缸筒与第一桥梁结构连接，活塞杆与刚性支座连接，缸筒还与软钢阻尼器连接，刚性支座及软钢阻尼器与第二桥梁结构连接；还包括切换装置，切换装置将“活塞杆与刚性支座连接”状态切换为“缸筒与软钢阻尼器连接”状态。
