| 中文摘要 | 江西吉安赣江大桥为三跨钢管混凝土拱桥,钢管拱肋为三角形截面,桥面与拱肋之间采用吊索连接以传递桥面荷载。吊索与钢管拱的连接节点设计是大桥建设中的一个技术难题。采用新型的外置索座式节点设计,介绍了节点的修改设计过程,运用有限元方法建模,分析比较了3种方案的优缺点,综合各方面的因素,最终选择了较为合理的方案。该方案满足结构承载力和变形要求,施工较方便,应用于工程实际取得了良好的效果。; Jiangxi Ji'an Bailu Bridge is a concrete-filled tubular arch bridge with 3 spans and triangular-sectioned tubular arch rib. The cable is adopted to connect deck and arch rib in order to transfer the deck loads. The design of the joints between the cable and the arch becomes a puzzle. This paper employs the creative design of straddling joints, applied for the first time in the world. The revised procedure is introduced, and the finite element method is used to model and analyze the joints. The merits and drawbacks of three schemes are analyzed. Considering many-sided factors, a reasonable design is selected. The design fulfills the requirement of ultimate bearing capacity and deformation, the construction of it is easy and a good performance is obtained after the application. The design provides a useful reference to the corresponding project.; 教育部优秀青年教师教学科研奖励计划资助项目(A0110719950102). |
