| 摘 要： | 高桩码头是码头建筑物中应用最广泛的结构形式,利用高桩码头物理模型振动测试结果对码头结构有限元模型的修正进行研究。以结构特征灵敏度分析为基础进行了基于优化理论的有限元模型修正。修正后的有限元模型动力特性更趋近于实测值,同时为高桩码头结构的动力响应分析、损伤诊断和整体性评估提供基准。

| Abstract: | The high piled wharf is one of the most widely applied structure of wharf building. Structural vibration of the finite element model is updated by use of physical model test results of piled wharf in this paper. The finite element model is updated based on the restriction optimization theory for the sensitivity analysis of the structure characteristics. The dynamic characteristics of the updated finite element model are closer to the measured value, ideal for dynamic response analysis of damage detecting and for evaluation of high pile wharf structure. |
