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。
Based on the Second Dongting Lake Bridge , static and composite bridge decks with two types of longitudinal rib were analyzed by Result shows that (1) Compared with traditional orthotropic steel deck (OSD) , ite bridge decks have more advantages in static and fatigue properties and life - weight composite bridge deckwith open ribs basically avoid the shortcomings of a traditional OSD withopen ribs which is torsionally soft and not very efficient in distributing transverse lsive future.
