A New Damage Alarm Index Based on Frequency Deviation for Structural Health Monitoring

Abstract:

Based on the statistics probability of certain order frequenciy deviates from its normal range, this paper puts forward a new damage alarm index and corresponding damage alarming method for structural health monitoring. Demonstrating the feasibility of this method, this article introduces the damage alarming method to analize the benchmark steel frame in frequency domain. The results show the abnormal index and its corresponding alarming method defined in sense of statistics indicates the abnormity of corresponding test cases clearly.
