| 摘 要： | 提出了一种基于结构振动特性的两阶段损伤诊断方法,以国际结构控制协会与美国土木工程学会(IASC-ASCE)提出的健康监测Benchmark模型结构为例,对其在力锤脉冲激励和环境激励下的试验数据进行分析,对不同的损伤模式进行了损伤定位和损伤程度的估计。结果表明,在模型误差、测量噪声、质量与刚度分布不确定性等因素的影响下,该两阶段损伤诊断方法能够取得令人满意的损伤识别结果。

| Abstract: | In this paper,a two-stage structural damage diagnosis method is proposed.A benchmark problem proposed by the International Association for Structural Control and the American Society of Civil Engineers(IASC-ASCE)Task Group on Structural Health Monitoring is presented,and data from hammer-impact and ambient-vibration tests are analyzed.The damage locations and extent for different cases are estimated.It is shown that even under the influences of modeling error,measurement noises,mass and stiffness uncertainties etc.,the damage diagnosis results are also satisfactory. |
