Friction energy dissipater and ductile pier structure
The invention provides a friction energy dissipater and a ductile pier structure. The friction energy dissipater comprises an outer cylinder, a push rod, a piston, a friction sleeve and an elastic reset piece. The piston, the friction sleeve and the outer cylinder are coaxially arranged; the friction sleeve is sleeved outside the piston, the outer wall of the friction sleeve is in contact with the inner wall of the outer cylinder, and the friction sleeve and the outer cylinder can relatively slide; the push rod and the elastic reset piece are movably arranged at the two ends of the outer cylinder respectively, and the two ends of the piston bear acting force applied by the push rod and the elastic reset piece respectively to achieve overall sliding of the piston and the friction sleeve in the outer cylinder. The ductile pier structure is provided with the friction energy dissipater and comprises a bearing platform, a preset damage section and a pier section which are sequentially arranged in the height direction. The outer cylinder is embedded into the bearing platform, and the push rod is embedded into the pier section. The outer-layer reinforcement cage, the friction energy dissipater and the inner-layer reinforcement cage are sequentially arranged on the pier structure from outside to inside, and layer-by-layer damage energy dissipation of the pier structure from outside to inside can be achieved.
本发明提供了一种摩擦耗能器及延性桥墩结构，该摩擦耗能器包括外筒、推杆、活塞、摩擦套筒和弹性复位件；活塞、摩擦套筒和外筒同轴设置；摩擦套筒套设于活塞外部，摩擦套筒的外壁与外筒内壁的接触，二者之间可发生相对滑动；推杆和弹性复位件分别活动设置于外筒的两端，活塞的两端分别承受推杆和弹性复位件施加的作用力，用以实现活塞和摩擦套筒在外筒内部的整体滑动。该延性桥墩结构设有上述的摩擦耗能器，包括沿高度方向依次设置的承台、预设损伤段和桥墩段；外筒嵌入承台设置，推杆嵌入桥墩段设置。本发明通过在桥墩结构从外到内依次设置外层钢筋笼、摩擦耗能器和内层钢筋笼，可实现桥墩结构从外至内逐层损伤耗能。
