| 摘 要： | 以东平大桥为背景,采用桥梁专用有限元软件MIDAS/CIVIL建立全桥空间模型. 对各种工况进行计算,得出各种工况下的挠度值、应力值,评估其结构的安全性. 计算结果表明:该桥在设计荷载下的最大挠度值均小于规范规定值,在荷载组合下的最大应力未超过材料的屈服强度,并具有一定的应力安全储备.

| Abstract: | Dong ping bridge as the background in the paper, using a bridge-specific finite element software MIDAS / CIVIL Spaces to set up full-bridge model. On the calculation of a variety of conditions, deflection value and stress value under a variety of working conditions, to assess the safety of its structure . The calculation results show that: under the design load of the bridge, the maximum deflection value of less than the value of standardizing provisions, under the load combination the maximum stress does not exceed the material yield strength and have a certain stress safety margin. |
