ABSTRACT
In the sustainable society, concrete structures should retain safety structural performance to the future. When pre-stressed concrete (PC) beam received the chloride attack, the failure of them may occur by steel bar corrosion. In this study, for the purpose of investigating the structural performance decrease by the several deterioration, the loading test of full scale PC T-shape beam and the structural analysis to it were carried out. This PC beam was cut off from existing bridge. In this analysis, the several deterioration scenario of PC beam were prepared. As the result, the load-displacement curve of analysis was similar to experiment curve, when the measurement results such as compressive strength or pre-stressing force were used. Based on the comparisons, it was confirmed that the maximum load was influenced by mass reduction of PC bars.
