Evaluation of reinforcement effect of deteriorated PSC beam through cutting its external tendons

ABSTRACT: Recently, bridges for which maintenance needs to be mainly made are increasing rapidly on the expressways, due to the thickening of traffic, the increase of large-sized passing vehicles and the increase of the period for public use. The prestressed concrete (PSC) beam bridge, which is about 25% of the whole bridges on the expressways, is the bridge of a representative type which assumes the most proportions among bridge types.
