发布时间:2018-09-06 10:09
【摘要】:以在建洞庭湖二桥为工程背景,建立两种纵肋形式的轻型组合桥面板局部有限元模型,对比分析了两类结构的静力和疲劳性能。结果表明:与传统正交异性钢桥面板相比,轻型组合桥面板的静力和疲劳性能均有一定程度的改善,且全寿命经济效益显著;带开口肋的轻型组合桥面板基本消除了传统开口肋正交异性钢桥面板的纵肋过柔,荷载横向分配能力较差等缺点,应用前景广阔。
[Abstract]:Based on the construction of Dongting Lake Bridge, a local finite element model of light composite deck slab with two longitudinal rib forms is established, and the static and fatigue properties of the two types of structures are compared and analyzed. The results show that compared with the traditional orthotropic steel bridge panel, the static and fatigue properties of the light composite deck are improved to some extent, and the economic benefit of the whole life is remarkable. The light composite deck slab with open ribbed ribs basically eliminates the shortcomings of the traditional orthotropic steel bridge slab with open ribs, such as the flexibility of longitudinal ribs and the poor capacity of transverse load distribution, etc., and has a broad application prospect.
