A New Abnormal Index Based on Frequency Change for Structural Health Monitoring

Abstract:

This paper demonstrates a new abnormal index based on frequency change for structural health monitoring (SHM) which utilizes probability and statistics method. And it was introduced to analyze a steel frame. The results show it could indicate the abnormity of corresponding test cases clearly.
