| 摘 要： | 空间结构分析在当今的桥梁结构计算中已经成为一种趋势,Code-Aster就是一款十分出色的结构分析软件。文中使用Code-Aste对桥梁进行空间分析计算,利用它内置的专业模块对桥梁上部结构的自重及预应力钢束张拉所引起的位移进行求解,并充分考虑了预应力损失和预应力钢束的张拉所引起的结构体系转换的问题。

| Abstract: | Spatial structure of the bridge structure has become a trend today',Code-Aster does a very good job on structural analysis.Here we uses Code-Aster to complete the calculation of a three-dimensional solid model of the bridge.By using its built-in professional block we can compute the displacement caused by the deadweight and prestressing force,and taking into account the loss of prestress and the system transformation caused by the pre-stressed tension. |

| Keywords: | spatial analysis Code-Aster prestress loss of prestres system transformation |
