摘要
以胜利大桥为背景,采用桥梁有限元分析软件MIDAS/CIVIL建立模型,对钢管混凝土拱桥成桥后的挠度值、应力值及结构的自振特性进行了分析。计算结果表明:该桥在设计荷载下的最大挠度值及应力值均小于规范规定值,结构处于安全的范围内。
Based on Shengli bridge, by using finite element software MIDAS/CIVIL build up a modal, the deflection, stress and natural vibration of completed concrete filled steel tubular arch bridge are analysised. The result show that:under the design load the maximum deflection and stress is less than code values, the bridge is safety.
