Abstract

 In this study, FE analysis for the girder ends with corrosion has been carried out in order to understand the failure mode and failure process . These collapse mechanism are analyzed from the analytical results, such as shapes of the deformation mode, stress distribution, and load-deflection relationships and so on. Using the load-deflection relationships diagram plotting the events such as buckling, tables of the failure modes, and a flow diagram of a failure process, the analysis cases were classified into six types of the failure type. By comparative analyzed of the failure mode and the the failure process and the difference of structural parameters to analyze the impact of the collapse, we examined the collapse mechanism of the corroded damaged steel girder end.
