BASIC FACTS CONCERNING SHEAR FAILURE

REPORTS ARE GIVEN ON TESTS OF RECTANGULAR BEAMS PERFORMED TO DETERMINE THE INFLUENCE OF THE THREE BASIC PARAMETERS IN EQ. /12-2/ & /17-2/ OF AMERICAN CONCRETE INSTITUTE 318-63. THE RESULTS SHOWED' /1/ THE INFLUENCE OF COMPRESSIVE STRENGTH ON SO-CALLED SHEAR STRENGTH WAS INSIGNIFICANT AND COULD BE IGNORED IN THE ANALYSIS OF DIAGONAL FAILURE LOAD OR ALLOWABLE SHEAR STRESS, /2/ THE INFLUENCE OF THE PERCENTAGE OF MAIN REINFORCEMENT ON SHEAR STRENGTH WAS CONSIDERABLE, /3/ THE MINIMUM VALUE OF BENDING MOMENT AT FAILURE FOR BEAMS OF IDENTICAL CROSS SECTION WAS OBTAINED IN THE VICINITY OF A SHEAR ARM RATIO OF 2.5, AND THIS WAS NOT INFLUENCED BY THE PERCENTAGE OF MAIN REINFORCEMENT OR THE COMPRESSIVE STRENGTH, HOWEVER, FLEXURAL LOAD CAPACITY VARIED CONSIDERABLY WITH PERCENT OF MAIN REINFORCEMENT, AND /4/ THERE EXISTS A CLEARLY DEFINED REGION BOUNDED BY LIMITING VALUES OF THE PERCENTAGE OF MAIN REINFORCEMENT AND SHEAR ARM RATIO INSIDE WHICH DIAGONAL FAILURE IS IMMINENT AND OUTSIDE WHICH FULL FLEXURAL STRENGTH IS ATTAINED. /AUTHOR/
