Abstract:

THE RESULTS OF EXPERIMENTAL STUDIES ON AXIALLY LOADED CYLINDERS AND THE CAMBER AND DEFLECTION OF SIMPLY SUPPORTED RECTANGULAR PRESTRESED CONCRETE BEAMS ARE REPORTED. THE CYLINDERS AND BEAMS WERE INITIALLY LOADED FOR A PERIOD OF 450 DAYS. SUBSEQUENTLY, THE LOADS WERE REMOVED, AND THE BEAMS AND CYLINDERS WERE LEFT WITHOUT LOADS FOR 90 DAYS AND THEN WERE RELOADED TO THE ORIGINAL STRESS FOR 90 DAYS. THIS SEQUENCE WAS REPEATED FOR ANOTHER CYCLE. THE MODULUS OF ELASTICITY IS OBSERVED AT DIFFERENT TIMES. VALUES FOR ULTIMATE SHRINKAGE STRAINS AS WELL AS ULTIMATE CREEP COEFFICIENTS ARE SUGGESTED. MATHEMATICAL MODELS FOR CREEP, CAMBER, AND DEFLECTIONS ARE DISCUSSED. THE EFFECT OF LOADING AGE IS OBSERVED AND A STATISTICAL EVALUATION OF DEFLECTION DATA IS PERFORMED. /AUTHOR/
