基于动力参数的桥梁工程结构损伤识别分析
|
摘要
阐述了近几年基于结构动力参数的桥梁工程结构损伤识别的方法,对这些方法进行了评议,指出了在理论和实际应用中的优点及存在的问题.对一试验模型的模拟损伤进行了分析,认为:结构损伤前和不同损伤程度的各工况所获得的模态参数都不相同.并通过分析说明了动力参数检测方法的应用.
An explanation is given,based on kinetic parameters,about the methods of the damage identification of bridge structures in recent years,and a comment is made on them.Pointed out are the merits and problems existing both in theories and practical application.After an analysis is carried out on the simulation damages of a test model,the view is held that there are quite differences among the modal parameters obtained under the working conditions before structural damages and in different damage degrees.Through analyzing,an explanation is made to the application of the kinetic parameter detection.
