| 摘 要： | 在钢箱梁的悬臂板外侧加设具有流线型的弧形钢板,使悬臂板部位构成封闭的空间,可提高抗锈蚀性,同时也满足城市桥梁美观的需求.以一座具有弧形腹板的连续钢箱梁城市高架桥为背景,建立全桥空间板壳有限元分析模型,研究具有大宽跨比特点的连续钢箱梁在不同设计荷载组合工况下,以及考虑桥面铺装钢纤维混凝土参与工作后,箱梁顶板的剪力滞效应.得出剪力滞系数沿横向、纵向的分布规律,以及考虑钢纤维混凝土桥面铺装后剪力滞系数的分布规律.

| Abstract: | The adding of streamlined arc shape steel plates to the outer side of cantilever plate of a steel box girder can make the part at the cantilever plate form a closed space,improve the rust resistance of the girder and at the same time satisfy the aesthetic requirements for city bridges. Against the background of a continuous steel box girder city viaduct that has arc shape webs,this paper sets up a spatial plate and shell finite element analysis model for the overall bridge and investigates the shear lag eff... |
