摘要
借助有限元软件,建立某连续刚构弯桥的三维仿真分析模型,通过对不同曲线圆心角引起的结构受力和变形进行比较,归纳出圆心角对于大跨径连续刚构弯桥静力特性的影响,对大跨连续刚构弯桥的设计和计算提出相应的建议。
With the help of finite element software, this paper establishes a three-dimensional simulation model of some continuous rigid structure curved bridge, generalizes the influences of central angles on static characteristics of large-span continuous rigid structure curved bridge by comparing the force and deformation of structure caused by central angles of different curves, and proposes corresponding recommendations for design and calculation of large-span continuous steel structure curved bridge.
