摘要
以某三跨城市匝道连续梁桥为研究对象,介绍了曲线钢箱梁桥的构造、设计要点,并采用Midas软件建立空间有限元模型,对墩梁固结各支座反力,以及基本组合下的应力、挠度、抗疲劳性能等进行了分析计算,可为同类桥梁设计提供参考。
Taking a three-span urban ramp continuous girder bridge as the research object, this paper introduces the structure and design essentials of curved steel box girder bridge. The Midas software is used to establish the spatial finite element model in order to analyze and calculate each support reaction of pier and girder consolidation, and the stress, deflection and anti-fatigue performance under the basic combination,which can be referred for the design of the similar bridges.
