PART 3C DEFLECTIONS OF PRESTRESSED CONCRETE BEAMS

THE EFFECT OF CREEP AND SHRINKAGE ON THE DEFLECTION CHARACTERISTICS OF PRESTRESSED CONCRETE BEAMS WAS STUDIED IN THE LABORATORY. DEFLECTION WAS DETERMINED BEFORE AND AFTER PRESTRESS TRANSFER AND AFTER A PERIOD OF LIVE LOADING. AT THE SAME TIME CREEP AND SHRINKAGE DATA WERE TAKEN ON CONCRETE PRISMS AND CYLINDERS. THESE EXPERIMENTAL DATA WERE COMPARED WITH DEFLECTIONS PREDICTED BY TWO THEORETICAL METHODS IN CONJUNCTION WITH THE CREEP COEFFICIENTS AND THE SHRINKAGE POTENTIALS OBTAINED FROM COMPANION SPECIMENS CAN PREDICT DEFLECTION DURING ALL STAGES OF LOADING OF PRESTRESSED CONCRETE BEAMS WITH REASONABLE ACCURACY.
