Periodic composite structure vibration reduction type bridge tower
The invention relates to a vibration reduction type bridge tower with a periodic composite structure, and belongs to the field of vibration reduction and isolation structures. The vibration reduction type bridge tower with the periodic composite structure comprises a bridge tower base body and scatterers, a plurality of scatterers are arranged on the bridge tower base body; the scattering bodies are periodically arranged on the bridge tower base body; on the basis of the periodical arrangement mode, the scatterers in a certain area periodically arranged in the bridge tower base are divided and adjusted, local aperiodicity is formed, and therefore the vibration reduction and isolation requirements are met. According to the periodic composite structure vibration reduction type bridge tower provided by the invention, on the basis of not adding other ancillary facilities, the periodic composite structure vibration reduction type bridge tower realizes vibration control on a special position and a special frequency band by utilizing the band gap characteristic and the passband frequency characteristic of the periodic composite structure vibration reduction type bridge tower and changing the characteristics of the structure of the periodic composite structure vibration reduction type bridge tower; and the structural performance of the bridge tower is reserved to the greatest extent. In addition, the whole structure is simple, the manufacturing is convenient, the cost is low, and the construction is easy.
本发明涉及一种周期复合结构减振型桥塔，减振隔振结构领域。该周期复合结构减振型桥塔包括桥塔基体、散射体；所述的桥塔基体上布置若干个散射体；所述的散射体在桥塔基体上的排列方式为周期性排列；在周期性排列方式的基础上，对桥塔基体中周期性排列的某区域散射体进行划分调整，形成局部非周期性，以满足减振隔振要求。本发明提供周期复合结构减振型桥塔，周期复合结构减振型桥塔在不附加其他附属设施的基础上，利用自身的带隙特性和通带频率特性，通过改变自身结构的特性实现对特殊位置、特殊频段的振动控制，最大程度上保留了桥塔本身的结构性能。此外，整体结构简单、制造方便、成本低廉、施工简易。
