以某立交匝道弯钢箱梁桥为研究对象,建立ANSYS的空间有限元实体模型,结合英国的BS5400及公路—I级荷载标准,对小曲率半径的弯钢箱梁桥进行了计算分析与设计探讨。总结得出此类弯钢箱梁桥在设计计算时的主要问题、关键控制点以及相应的解决措施,为同类桥梁的设计计算提供参考。
Taking a freeway curved steel box girder bridge as the research object, the space finite element model of ANSYS was established. Based on BS5400 and Highway-I load standard in the UK, the calculation and analysis of curved steel box girder bridge with small curvature radius Discussion. The main problems, critical control points and corresponding solutions in the design and calculation of such curved steel box girder bridges are concluded, which provide references for the design and calculation of similar bridges.
