最小弯曲能量法确定系杆拱桥成桥索力

Confirmation of Final Hanger Force in Tied Arch Bridge Based on Minimum Bending Energy Method

斜拉桥和系杆拱桥都基于三元构件,所以在结构分析中有一些通用的方法,尤其在成桥索力的确定问题上.基于斜拉桥成桥状态确定的思路和方法,以最小弯曲能量法确定系杆拱桥的成桥索力,并分析确定其合理性,为后续进一步优化及确定施工阶段吊杆索力提供可靠依据.

The cable-strayed bridge and the tied arch bridge are all based on the triple element , so they share some general methods in the structural analysis , especially when determining the completion state of cable force . Based on the thought and method to determine the completed status of the cable-stayed bridge , this paper uses the least bending energy method to evaluate the reasonable cable forces of the tied arch bridge and analyzes the rationality, providing the infallible data for further optimized suspender force .
