| 摘 要： | 利用ANSYS软件建立了粉房湾大桥索梁锚固区实桥模型,分析了耳板式锚固区结构的应力及应力分布情况,对承载能力进行了评价。结果表明:耳板上的Mises应力远大于顶板、腹板和底板的应力,耳板上最大Mises应力位于销孔的两侧,关于斜拉索方向对称的位置;锚固区各构件应力在局部区域数值较大,但扩散较快,应力传递流畅;满足索梁锚固区结构承载能力要求。

| Abstract: | By using the ANSYS,a 3-dimensional finite element model for the cable-beam anchorage zone of Fenfangwan Bridge was built to investigate the stress.The stress distribution was analysed and the bearing capacity was consequently evaluated.The following conclusions can be drawn: the stress on ear-plate is much greater than the other plates;the maximum Mises stress is located on the sides of pin hole;stress transfers fast and fluently though it is greater on some local regions;the structure could meet the requirements of bearing capacity. |
