Multi-stage energy dissipation damping device and offshore platform pile leg structure
The invention provides a multi-stage energy dissipation damping device which comprises a center pipe, damping units and connecting units, and fixing holes are formed in the two ends of the center pipe; the damping units are arranged at the two ends of the center pipe and comprise a plurality of slotted plates attached to the outer wall of the center pipe in the circumferential direction, each slotted plate is provided with an extending arm extending section, the extending direction is the direction from the middle of the center pipe to the two ends, the front ends of the arm extending sections are located outside the two ends of the center pipe, and the slotted plates are provided with fixing holes corresponding to the fixing holes of the center pipe. The connecting units penetrate through the fixing holes to fix the damping units to the two ends of the center pipe. The invention further provides an offshore platform pile leg structure, the offshore platform pile leg structure comprises the multi-stage energy dissipation damping device, and the offshore platform pile leg structure is a novel pile leg structure considering an energy dissipation time sequence, has good energy dissipation capacity and can bear complex deepwater area loads and uncertain earthquake action.
本发明提供了一种多阶段耗能阻尼装置，所述多阶段耗能阻尼装置包括中心管、阻尼单元、连接单元，其中，中心管的两端开设有固定孔；阻尼单元设置在中心管的两端，包括若干个沿周向贴合在中心管外壁上的开缝板，开缝板具有外延的伸臂段，外延方向为中心管中间指向两端的方向，伸臂段的前端位于中心管两端端部之外，开缝板设有与中心管的固定孔对应的固定孔；连接单元穿过固定孔将阻尼单元固定在中心管的两端。本发明还提供了一种海上平台桩腿结构，所述海上平台桩腿结构包含有所述多阶段耗能阻尼装置，所述海上平台桩腿结构为考虑耗能时序的新型桩腿结构，具有良好的耗能能力，可承受复杂的深水区域载荷及不确定的地震作用。
