Health Assessment of Prestressed Girder by Deterioration Processes Evaluation

摘要

This study aims at non destructive procedure development for the health condition ofprestressed/post tensioned concrete bridges evaluation and damage development assessment duringproof loading. This evaluation includes the assessment of damage severity and extension in thedeteriorated zones of structure together with defects localization. While most of NDT methods dealwith defect detection and size estimation, in presented procedure the evaluation is performed on thebasis of deterioration processes that take place under service conditions of tested structures. Theadvantages of this procedure among other are: deterioration severity assessment, on line monitoring,results codification that fit into the traditional bridge reports, the results reflects the factors thatinfluence reliability of structure, severity and extension deterioration evaluation in structure.
