| 摘 要： | 首先针对基于动力特性和人工神经网络的桥梁结构损伤诊断研究情况作了简要介绍，主要工作是将动力特性参数作为神经网络的输入数据，以改进的频率和振型动力特性组合指标参数对钢桁架简支桥梁结构进行了损伤识别，识别结果表明对钢桁架简支桥梁的损伤位置识别误差较小，对损伤程度的识别效果稍差，识别方法还需要进一步改进。

| Abstract: | In this paper,the damage diagnosis of bridges based on dynamic characteristics and artificial neural networks is first briefly introduced.Then the dynamic characteristics parameters are input into the neural network.The damage detection of steel truss bridges with the improved natural frequency and vibration mode is carried out.The result shows that the recognition error in damage location identification of the steel truss bridge is small,while the recognition effectiveness in damage degree is found not sat... |
