正交异性钢桥面板的计算分析

Calculation Analysis of Orthotropic Steel Bridge Deck Slab

正交异性钢桥面板在钢桥尤其是大跨度钢桥设计中广泛使用。该文通过分析总结正交异性钢桥面板的计算方法,为设计人员在设计工作中提供参考。对比整体计算法和叠加计算法的优缺点,并通过工程实例,采用格子梁法详细分析了正交异性钢桥面板的计算过程,同时阐述了计算过程中的注意事项,指出整体计算法、P-E法和格子梁法三种计算方法中格子梁法更加高效,整体计算法最为准确。

The orthotropic steel bridge deck slab is widely used in the design of steel bridge,especially the long-span steel bridge.The article analyzes and sums up the calculation method of orthotropic steel bridge deck slab,which can be referred for the design work.According to the comparison of the advantages and disadvantages of the overall calculation method and the superposition calculation method,and the engineering cases,the gridwork girder method is used to analyze the calculation process of orthotropic steel bridge deck slab in detail.The article sets forth the attentions paid in the calculation process,and points out that the gridwork girder method is higher efficient in three methods of the overall calculation method,P-E method and gridwork girder method.The overall calculation method is the most correct one.
