Damage Alarming Method Based on Statistics to a Benchmark Structure

Abstract:

This paper addresses a new damage alarming method of structural health monitoring (SHM) which utilizes statistic method on information in frequency domain. The emphasis in this paper is on the application of this method to the benchmark structure by introduced an abnormal index. The results show this method could indicate the abnormity of corresponding test cases clearly.
