摘要
为对小跨径变截面斜腿刚架桥进行准确而简便的分析计算,采用梁格法并通过动静载试验与有限元计算结果进行验证,提出在建立梁格模型时应对计算跨径和斜腿刚域进行合理的模拟,所得结果满足精度要求.
In order to analyze the small-span of rigid frame bridge exactly and conveniently, we use the grid frame method and comparatively check the results with static and dynamic tests and finite element analysis. The calculation of span and rigid field for rigid frame bridge＇ s tilted leg is considered. We show that the simulation is more reasonable and the result is acceptable.
