| 摘 要： | 纵肋与横梁交叉部位处横梁弧形切口周边疲劳裂纹是正交异性钢桥面板的主要病害之一.采用有限元方法对钢桥面板横梁弧形切口周边应力分布及特点进行了分析.研究表明:横梁高度对引起该类型疲劳裂纹各作用的发挥有决定性的影响,对于高度较小的柔性横梁,横梁的整体行为效应占主导地位,疲劳敏感位置遍布整个剪跨段;高度较大的刚性横梁局部行为效...

| Abstract: | Fatigue crack initiating at the edge of cope hole in the crossbeam at the longitudinal rib-to-crossbeam joint is one of primary defects of orthotropic steel deck.The stress characteristic of the edge of cope hole in the crossbeam was analysed by employing finite element method.The results show that(1) The height of crossbeam has a significant influence on the role of various actions inducing this type of crack.The global effect of crossbeam predominates in relatively low flexible crossbeam,and the fatigue p... |
