摘要
以梯形及矩形截面形状的纵向加劲肋组合3种缺口类型的横隔板,建立正交异性闭口加劲钢桥面板有限元实体模型进行加载,用ANSYS程序计算分析了横隔板不同缺口形式的正交异性钢桥面板力学性能、正交异性钢桥面板、纵肋、横隔板三者连接处的应力状态以及不同缺口形式的正交异性钢桥面板疲劳性能,研究了横隔板缺口形式对正交异性钢桥面板静力力学性能以及疲劳性能的影响。
Combined with three typologies of cutout in diaphragm with longitudinal stiffeners trapezoidal and rectangular shape,establishment of orthotropic U-rib stiffened steel plate finite element model,loading,analysis and calculation of the diaphragm with different notch form of orthotropic steel bridge decks were,and mechanical properties of the orthotropic steel deck,longitudinal ribs,the connection of the three diaphragm the stress state and different notch form of orthotropic steel bridge decks fatigue performance were made by ANSYS. The effect of diaphragm gap on the orthotropic steel deck static mechanical properties and fatigue properties were researched.
