| 摘 要： | 对钢管混凝土系杆拱桥的拱肋在有限元分析中的模拟方法进行了探讨,并以一40 m跨的钢管混凝土系杆拱桥为算例,运用大型有限元软件M IDAS/C IVIL对该桥进行全桥计算,主要考察了钢管混凝土拱肋在施工过程中各种模拟方法的异同和管内混凝土收缩徐变对钢管混凝土系杆拱桥拱肋的影响,通过对计算结果的比较分析,得出一些有指导意义的结论。

| Abstract: | This article explores the simulation method in finite element analysis of arch rib of concrete-filled steel tube tied-arch bridge.Taking 40 m span concrete-filled steel tube tied-arch bridge as the example,applying large-scale finite element software MIDAS/CIVIL,it carries on whole bridge calculation,mainly inspects the similarities and differences of various simulation methods of concrete-filled steel tube tied-arch bridge in the construction process and the impacts of internal tube concrete creep and shrinkage on concrete-filled steel tube tied-arch bridge arch rib.Through comparing and analyzing calculation results,it obtains some guiding conclusions. |
