| 摘 要： | 进行了第一座钢管 - 钢管混凝土复合拱试验桥--福建福鼎山前大桥实桥静载测试和有限元模拟分析,对钢管-钢管混凝土复合拱静力性能进行了讨论,研究表明,复合拱的静力性能与等截面拱相近,但拱肋变截面处应变应是设计中的控制因素,极限承载力分析应考虑双重非线性的影响.

| Abstract: | A field static load testing and an FEM analysis were conducted on the first hybrid arch bridge of steel tube and concrete filled steel tube, Fuding Shangqian Bridge, in Fujian Province. A detailed discus sion of the testing results and analysis results indicated that the behavior of the hybrid bridge is similar to that of a constant cross-section bridge. However, the strain of arch rib in varying cross-section would be the control factor in design. Therefore, both geometrical and material nonlinearities should be taken into account in predicting the ultimate load carrying capacity. |
