Abstract

<p>This paper introduces the details of a newly proposed “State Representation Methodology (SRM)” and its application to bridge condition assessment based on the bridge monitoring data. The SRM combined with the frequency slice wavelet transform (FSWT) which is a new time-frequency analysis tool was proposed for assessing a bridge condition based on the bridge monitoring data. This paper describes at first an overall description of SRM method via FSWT analysis. Then it will be demonstrated not only some new properties and advantages of FSWT analysis in contract to the traditional wavelet but also how accurate on feature extracting of SRM analysis for damage detection in a bridge system based on its monitoring data by using digital experiments.</p>
