Load-Carrying Capacity of post-tensioning PCT girder damaged by chloride

Abstract

For post-tensioning PCT girder damaged by chloride, it was subjected to load carrying-capacity evaluated by loading test and numerical analysis. As a result, In the loading test which properties of the PC steel, if the grout is good adhesion of the PC steel and concrete, it was found that contribute to the load-carrying capacity. also, In the numerical analysis of the individual damage with a parameter, the influence of cross-section reduction by steel corrosion was confirmed which greatly affects the load-carrying capacity.
