| 摘 要： | 结合武广客运专线东平水道(99+242+99)m四线三主桁连续钢桁拱桥的建设,采用有限元软件ANSYS中的板单元对中桁E11整体节点进行局部应力分析,结果表明设计结构中存在局部应力过大的现象.为此对结构设计进行了修改.改进节点构造后,该节点具有足够的受力与传力功能.

| Abstract: | With the construction of Dongpingshuidao Bridge is a four-line truss arch bridge with span of(99+242+99)m in the Wuhan-Guangzhou high-speed railway,integral joint E11 in middle truss is analyzed by using shell element in the ANSYS,local stress has been founded too strong in the structure.In order to resolve this problem,joint design has been modified.The improvement of the joint makes it have the sufficient function of bearing and transfer force by improving the node structure. |
