UNDERSTANDING THE RELAXATION IN PRESTRESSING

RELAXATION IS DISCUSSED IN PRESTRESSING STEEL WIRE, DEFINED AS STRESS LOSS AT CONSTANT EXTENSION AND RELATED TO CREEP PHENOMENON. BOTH RELAXATION AND CREEP ARE CORRELATED TO THE STRESS-STRAIN DIAGRAM. THE EFFECTS OF TIME TEMPERATURE, RATE OF LOADING AND RE-STRESSING UPON RELAXATION ARE PRESENTED. /PCIJ/
