摘要
根据曲线箱梁力学行为为曲梁特征的特点 ,将围成闭口截面曲线箱梁的板件视为曲线板梁 ,由此提出了薄壁曲线箱梁空间计算的曲板板梁单元法 ,此方法自由度少 ,计算精度较高 ,且计算思路与方法较简洁 ,物理概念明确 。
The deckle boards of curved box girder are taken as curved plate beams according to the fact that the box girder mechanics behavior is the curved beam characteristic, and a curved plate beam element method of spatial computation for thin walled curved box girder is presented. This method has high accuracy and less degrees of freedom. The train of thought and the computation are simple and the physical concepts are very clear, especially for the spatial computation of the large cured multi cell box girder structure.
