| 摘 要： | 有效宽度是薄壁梁桥应力设计计算中的一个主要问题。文章以一座在建的三跨（29．3＋50＋29．3）m连续梁桥为研究对象，利用有限元分析软件建立实体模型，研究不同荷载工况下变截面连续梁有效宽度的分布规律，并与现行规范的有效宽度进行对比分析，其结果可为变截面连续薄壁梁的设计和施工提供指导。

| Abstract: | The effective width is a major problem in the stress design calculations of thin-walled girder bridge.With a three-span（29. 3＋ 50＋ 29. 3） m continuous girder bridge under construction as the research object,this article used the finite element analysis software to establish the solid model, and studied the distribu- tion regularity of the effective width of con-tinuous beam with variable sections under different load conditions, and conducted the comparative analysis with the effective width in existing specifications,and its results can provide the guidance for the design and construction of continuous thin-walled beams with variable sections. |
