CREEP AND DAMPING CHARACTERISTICS OF CONCRETE

THE REPORT PRESENTS THE RESULTS OF DYNAMIC TESTS ON CONCRETE CYLINDERS TO DETERMINE DAMPING CHARACTERISTICS, AND ATTEMPTS TO RELATE THESE RESULTS TO CREEP IN PLAIN CONCRETE. TESTING CONSISTED OF PRODUCING AN IMPACT LOADING ON THE CYLINDERS, PICKING UP THE IMPULSES WITH ACCELEROMETERS AND MONITORING THE DECAY CURVES ON AN OSCILLOSCOPE. PICTURES OF THE CURVES WERE TAKEN WITH A POLARIOD CAMERA. LOGARITHMIC DECREMENTS DECREMENTS WERE SUBSEQUENTLY CALCULATED FROM THE PICTURES. THE RESULTS WERE COMPARED TO NUMEROUS CREEP THEORIES DEVELOPED FROM MECHANICAL MODELS. IT WAS CONCLUDED THAT NO SIMPLE CORRELATION EXISTS BETWEEN THE LOGARITHMIC DECREMENT AND THE ULTIMATE CREEP OF CONCRETE, BUT THE HYPERBOLIC EXPRESSION PROPOSED BY ROSS SATISFACTORILY PREDICTS THE ULTIMATE SPECIFIC CREEP OF CONCRETE. /BPR/
