正交异性钢桥面板的结构分析

Structural Analysis of Orthotropic Steel Bridge Deck

在具有相同截面面积的开口纵肋和闭口纵肋钢桥面板静力试验的基础上，提出简化的计算模型，并采用有限元法进行精确的应力分析，计算结果与试验结果符合良好；系统地论述了正交异性钢桥面板弹性阶段的应力特性，着重研究了构造布置对铺装应变的影响，从而对铺装提出合理可行的建议．

A simplified model is proposed on the basis of the static tests of two types of ribs having the same area of cross section. Stress analyses are carried out with the finite element method. The calculated results show good agreement with the experiment results. The stress behaviour of orthotropic steel bridge decks under elastic phase is systematically discussed. Strain of pavement influenced by the arrangement of structure is emphatically studied. And the deliberate suggestions about the pavement problem are put forword.
