| 摘 要： | 对一座钢管混凝土拱桥,进行了空间有限元模拟分析,应用大型通用有限元程序ANSYS对大桥建立了模型,解决了桥梁细部诸如支座、刚臂等细节的处理;最后对大桥的有限元模型进行了动力特性计算,得到了振型、频率的数据,可以对大桥的动力性能做出评价,有助于今后建立大桥的档案和健康诊断评估。

| Abstract: | The paper analyzes a steel piped concrete arch bridge for space finite element simulation,establishes a model for bridge by large-scale current finite element program ANSYS,has accomplished treatments for the bridge details such as pedestal rigid arm etc,computed dynamic properties for bridge's finite element model,obtaining the data of oscillating mode and frequence,which could estimate the dynamic properties of bridge and be advantageous to set the file and the health diagnosis for bridge in the future. |
