Abstrakt:

There have been many reports released on failure of prestressing steels due to corrosion. This is taken seriously in that it can cause sudden collapse of the structure. In this paper, experimental investigation was performed to evaluate the performance of prestressed concrete beams. The strands of the specimens were electro-chemically corroded with Impressed Current Method (ICM). Location of corrosion, degree of corrosion, and the number of corroded strands are the parameters considered herein. The test result shows strength reduction of a centrally corroded PSC beam, but not in the other location near anchorages. Based on the analytical solutions using mechanical models of corroded strands with different pit depth, the flexural strength of the PSC beams was assessed. A procedure to assess the influence of the corroded strand on the behaviour of a PSC beam is suggested.
