STUDY ON CHARACTERISTICS OF PC CRACKS DUE TO CORROSION OF PC SHEATH

Abstract

 This paper is descraibed the occurrence tendency of cracks by corrosion of the PC sheath arranged in the PC structures. To investigate these, an experiment by electrically corrosion and numerical analysis by an FEM were performed.
 It is found that insufficiently grouted influences a crack of a PC by corrosion of a steel sheath. Therefore the consideration which imitated the insufficiently grouted situations assumed by existing structures was performed.
 It was proposed that insufficiently grouted investigation method in the PC structure which occurred due to corrosion of a steel sheath based on an obtained result.
