High-toughness concrete plastic hinge structure pier column for cable-stayed bridge
The invention discloses a high-toughness concrete plastic hinge structure pier column for a cable-stayed bridge, which comprises a pier column body, box-type pier column bodies are arranged on the two sides of the top and the bottom of the pier column body, and plastic hinges are fixedly arranged between the box-type pier column bodies; the plastic hinge comprises an anchoring connection section, a transition section and a standard section, and the anchoring connection section, the transition section and the standard section are all of box-shaped structures and are made of high-toughness concrete. The anchoring connection section is fixed with the box-type pier column, and the wall thickness of the anchoring connection section is the same as that of the box-type pier column; the standard section is located in the middle of the plastic hinge, and the wall thickness of the standard section is smaller than that of the anchoring connecting section. The transition sections are located at the two ends of the standard section and fixed between the anchoring connection section and the standard section, and the wall thickness of the transition sections is reduced from one side of the anchoring connection section to one side of the standard section. The invention aims to provide the plastic hinge structure pier column which is high in bending performance, capable of reducing the construction cost and suitable for the cable-stayed bridge.
本发明公开了一种斜拉桥用高韧性混凝土塑性铰构造墩柱，包括墩柱，所述墩柱顶底两侧为箱型墩柱，箱型墩柱之间固定设置有塑性铰；所述塑性铰包括锚固连接段、渐变段和标准段，锚固连接段、渐变段和标准段均为箱型结构且由高韧性混凝土构成；所述锚固连接段与箱型墩柱相固定，锚固连接段与箱型墩柱的壁厚相同；所述标准段位于塑性铰的中部，标准段的壁厚小于锚固连接段；所述渐变段位于标准段的两端并固定于锚固连接段与标准段之间，渐变段的壁厚由锚固连接段一侧向标准段一侧降低。本发明旨在提供一种弯曲性能高，能降低建造成本，适用于斜拉桥中的塑性铰构造墩柱。
