A Structural Damage Alarm Index Based on the Statistical Probability of Abnormal Frequency Offset

摘要：

　　Based on the statistical probability of abnormal frequency offset, this paper puts forward a new structural damage alarm index.Demonstrating the feasibility of corresponding structural damage alarming method, this article introduces the index to analize a steel frame structure in frequency domain.The results show the abnormal index defined in sense of statistics indicates the abnormity of corresponding test cases clearly.
