| 摘 要： | 以江东大桥为背景,对自锚式悬索桥索梁锚固区借助通用有限元软件建立锚固区的精细板壳模型,研究锚同区各板件在最不利荷载组合作用下的受力特性,根据各板件的应力应变关系模型,分析锚箱结构的极限承载能力.计算结果表明:钢锚箱应力沿着传力路径由锚固位置向加劲梁方向逐渐减小.在最不利荷载组合作用下,Mises应力最大值为144 MP...

| Abstract: | In design of the Jiangdong Bridge,by using the fine shell element model,a Finite Element study is carried out to investigate the behavior of joints of girder to cables for this self-anchored suspension bridge under the most adverse load combinations,and the bearing capacity of these anchored joints are analyzed in accordance with the stress and strain relationships inherent in each individual panel component.The FE results illustrate that stress in the steel anchored box decreases along the load transverse ... |
