Abstract

This study examined the effects of corroding process under loading on the ultimate strength of the plate girder. In order to simulate the behavior of the corroded girder under loading, a series of the elastic-plastic large deformation analyses was carried out by using the FEM program, which had developed based on the shell element, with considering the stress redistribution due to loss of thickness. As results, the effects of corroding process under bending and shearing on the ultimate strength and the deformation of the plate girder were small. Therefore, it was concluded that the ultimate strength and the deformation could be predicted without monitoring the change of thickness in the corroding process.
