EFFECT OF STRESS ON THE DYNAMIC MODULUS OF CONCRETE
RESULTS ARE PRESENTED OF A PRELIMINARY INVESTIGATION OF THE EFFECT OF STRESS INTENSITY ON THE MODULUS OF ELASTICITY OF CONCRETE. STRESS-STRAIN DIAGRAMS ARE SHOWN WHICH WERE CONSTRUCTED FOR STATIC TESTS AND BY USING THE VIBRATORY DATA FOR TRANSVERSE RESONANT VIBRATIONS AT VARIOUS STRESS INTENSITIES. THE VARIOUS TESTS WERE PERFORMED ON THE SAME CYLINDERS, THEREBY USING THE SAME SPECIMEN FOR BOTH THE VIBRATORY AND STATIC TESTS. THE VIBRATORY TEST IS AN ADAPTATION OF ASTM C215-60 WITH THE SPECIMENS VIBRATED IN THEIR TRANSVERSE MODE. THE RESULTS OF THIS INVESTIGATION INDICATE THAT THE DYNAMIC MODULUS OF ELASTICITY INCREASES AS THE INTENSITY OF STRESS ON THE SPECIMEN INCREASES. THE INCREASE IN THE DYNAMIC MODULUS OF ELASTICITY VARIED FROM 7 TO 18 PERCENT FOR DIFFERENT STRENGTH SEPECIMENS WHEREAS THE CORRESPONDING DECREASE IN THE STATIC TANGENT MODULUS WAS 54 AND 7 PERCENT FOR THE SAME SPECIMENS. /AUTHOR/
