STATISTICAL STUDY OF PRESTRESSED CONCRETE, USED IN ENGINEERING STRUCTURES, AND EXPERIMENTAL DETERMINATION OF THE LOSS OF STRESS IN PRESTRESSING STEEL CAUSED BY DELAYED PHENOMENA AND DETERMINATION OF THE PART PLAYED BY PURE RELAXATION OF STEEL IN THAT LOSS /IN FRENCH/

DETAILS ARE GIVEN OF A STATISTICAL STUDY OF CONCRETE IN SEVERAL PRESTRESSED CONCRETE STRUCTURES TO DETERMINE THE CHARACTERISTICS OF CONCRETE AND ITS EVOLUTION IN TIME, AND TO INVESTIGATE THE EXTENT AND EVOLUTION OF DELAYED PHENOMENA (SHRINKAGE AND CREEP). RESULTS SHOW THAT THE EFFECTS OF CREEP AND SHRINKAGE MUST BE CLEARLY SEPARATED IN THE CALCULATIONS FROM THOSE OF STEEL RELAXATION. NEW RECOMMENDATIONS ARE PROPOSED TO REPLACE PRESCRIPTIONS FOR DEFINING THE CHARACTERISTICS OF VARIOUS STEELS. /LCPC/RRL/
