| 摘 要： | 斜拉桥的桥面结构有效宽度在桥梁设计规范中没有明确给出。以金马大桥为研究背景 ,通过建立平面和空间有限元模型 ,在多种荷载工况下计算分析了这种双主梁式斜拉桥主梁的有效宽度 ,并得出在对称荷载作用下桥面板正应力趋于均匀分布的结论。这为同类边主梁结构形式的斜拉桥提供了很好的设计依据。

| Abstract: | There is no exact answer in bridge design regulation for efficient width of main girder for cable stayed bridges.Taking Jinma bridge as an example, the efficient width of the main girder under the multi load conditions was calculated by constructing 2D and 3D modals with limited element theory.The results show that the stresses of the deck under symmetric loads are smooth.It offers a good design foundation for the cable stayed bridges which have the same edge girder structure with Jinma bridge. |

| Keywords: | cable stayed bridge shear lag effecte efficient width |
