摘要:
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,为各国所首次采用。通过有限元方法建模,对终选方案节点进行在多种工况下的承载力分析,研究了其应力分布及变形特征,并提出实施时的改进意见。计算分析结果表明:该方案满足结构承载力和变形要求,施工难度较小,同时与现场原型试验结果吻合也较好。该新型节点工程在实际应用中也取得了良好的效果,可为相关工程提供有益的参考。
Abstract:
The design of the joints between the cable and the arch is a difficult technological problem in the bridge construction. Authors employed the creative design of outer cable joints, which was applied for the first time in the world. By using finite element software, the ultimate capacity of joints under various load cases was calculated and the stress distribution was analyzed, which directed the application of the joints. The design fulfills the requirement of ultimate capacity and deformation, the construction of it which is easy and a good performance is obtained after the application. Also, the calculation results of the analysis are in good accord with those of the full-scale tests in site, and the design provides a useful reference to the corresponding project.
