摘要
现浇箱梁具有良好的受力性能,在城市高架桥设计中应用广泛,当某些匝道桥支座间距受限时,横向稳定性则可能出现问题。采用Midas对工程实例进行结构分析,发现原设计中存在的问题,并分析发生横向倾覆的主要因素,提出对该类桥的改进方法。
The cast- in- situ box girder behaviors. However, for some ramp bridges the limited. In this paper, Midas software is the original design, and analyze the main these kinds of bridges. used to is widely used in urban vi lateral stability problem may analyze the practical enginee factors of lateral overturning. Finally, aduct because of good mechanical occur when the bearing spacing is ring example, find the problems in improved methods are proposed for
