Large-cantilever canopy in-column prestress inhaul cable vibration reduction structure system and design method
The invention discloses a large-cantilever canopy in-column prestress inhaul cable vibration reduction structure system and a design method. The large-cantilever canopy in-column prestress inhaul cable vibration reduction structure system comprises a canopy, a front strut is connected below the middle rear section of the canopy, the rear end of the canopy is connected with a hollow vertical tail column, a prestress inhaul cable is arranged in the tail column, one end of the prestress inhaul cable is connected with the rear end of the canopy, the other end is archored and fixed, the tail columnis provided with a spring damping support capable of achieving vertical vibration reduction, or a spring damping support capable of achieving vertical vibration reduction is arranged between the topof the tail column and the rear end of the canopy, and a through hole is formed in the spring damping support, so that the prestress inhaul cable penetrates through the through hole of the spring damping support and can slide relative to the spring damping support. Building materials are reasonably utilized to resist overturning, the safety requirement for tension of a building structure under thenormal working condition can be guaranteed, the safety requirement for compression of the building structure under the abnormal working condition can also be guaranteed, and meanwhile the view of audiences is not affected.
本发明公开了一种大悬臂挑篷柱内预应力拉索减振结构体系及设计方法，包括挑篷，挑篷的中后段下方连接有前支柱，所述挑篷的后端连接有中空的竖向尾柱，尾柱内部设置有预应力拉索，所述预应力拉索一端连接所述挑篷的后端，另一端锚固固定，所述尾柱自身具有可竖向减振的弹簧阻尼支座或者所述尾柱顶与所述挑篷的后端之间设置有可竖向减振的弹簧阻尼支座，所述弹簧阻尼支座开设有通孔，使所述预应力拉索从所述弹簧阻尼支座的通孔穿过并能够相对所述弹簧阻尼支座滑动。本发明通过合理利用建筑材料来抵抗倾覆，既能保证常态工况下建筑结构受拉的安全要求，也能保证非常态工况下建筑结构受压的安全要求，同时不影响观众视野。
