大跨度钢箱梁焊接变形计算分析

The Welding Deformation Analysis of a Long-span Steel Box Girder

对大跨度钢箱梁焊接变形计算分析的方法和原理进行了归纳总结,采用有限元软件进行了系统的计算。以上海中环线汶水路高架桥工程为例,对大跨度钢箱梁焊接变形计算分析的方法和原理进行了系统的论证,实际施工的结果证明了该方法的可行性。

Based ysis method and formation example, using on the induction and summarization of the welding deformation computation and analprinciple for long-span steel box girder, the paper systematically finite element software. Taking the Shanghai Central Wenshuilu vi the paper systematically demonstrated the welding deformation comput method and principle, whose feasibility was proved by the practice computed the deaduct project as an ation and analysis
