Pipe-in-pipe type tuned mass damper for restraining wind-induced vibration
According to the pipe-in-pipe type tuned mass damper for restraining the wind-induced vibration, the pipe-in-pipe mass column, the installation support, the spring and the damper are all located in the inner cavity of the pipe body structure, excellent environmental adaptability is achieved, the damper can still effectively work under various complex meteorological conditions, the frequency of maintenance and replacement is reduced, and the service life of the damper is prolonged. The overall operation cost is reduced; due to the arrangement mode in the pipe body structure, the structural load is more uniform, and the problem of structural instability possibly caused by additional mass is effectively reduced, so that the overall stability of the high-rise structure is enhanced; the tuned mass damper can more effectively participate in resonance absorption and dissipation of external vibration energy, so that the vibration energy is fully absorbed or dissipated in the damper, and the problem that the tuned mass of a traditional tuned mass damper is limited is solved.
本发明提出了一种抑制风致振动的管中管型调谐质量阻尼器，管中管质量柱、安装支架、弹簧和阻尼器均位于管体结构的内部空腔内，具备优越的环境适应性，使其在各种复杂气象条件下仍能有效地工作，减少了维护和更换的频率，降低了整体运营成本；而且管体结构内设置的方式，使得结构负载更加均匀，有效降低附加质量可能引发的结构性失稳问题，从而增强了高耸结构整体的稳定性；本发明可以更有效地参与共振吸收和耗散外部振动能量，从而在阻尼器中充分吸收或耗散振动能量，解决了传统调谐质量阻尼器的调谐质量受限的问题。
