Abstract
In this research, we conducted loading tests of pre-tension prestressed concrete (PC) girder which had been deteriorated due to chloride attack. Because distribution of corrosion of PC strands was different in each girder, failure mode and structural performance were also different.
As next step, we conducted the evaluation of the residual strength of girder with Finite Element (FE) analysis. If the weight loss of PC strands were carefully considered based on the measurement results, numerical results succeeded to simulate loading test by using adequate constitutive model for corroded PC strands. In contrast, it was found that the accuracy of evaluation reduces if the degree of corrosion of PC strands were estimated from external cracks of girder.
