DIAGONAL CRACKING STRENGTH IN SHEAR OF REINFORCED CONCRETE

IT HAS BEEN SHOWN IN RECENT YEARS THAT THE AMERICAN CONCRETE INSTITUTE CODE FORMULA (WHICH HAS BEEN ADOPTED IN THE AUSTRALIAN DRAFT CODE) FOR PREDICTING DIAGONAL CRACKING SHEAR IS INADEQUATE, ESPECIALLY FOR SMALL VALUES OF P, THE LONGITUDINAL TENSION STEEL RATIO. IN THIS PAPER, THE PRINCIPAL TENSILE STRESS AT THE NEUTRAL AXIS OF A FLEXURALLY CRACKED BEAM IS CONSIDERED AS THE PRIMARY CAUSE FOR DIAGONAL CRACKING, AND A FORMULA IS DERIVED FOR THE CALCULATION OF THE DIAGONAL CRACKING SHEAR IN REINFORCED CONCRETE BEAMS. COMPARISONS WITH OVER FIVE HUNDRED TEST RESULTS SHOW THAT THIS FORMULA IS A BETTER SHEAR STRENGTH PREDICTOR THAN THE ACI FORMULA FOR WIDE RANGES OF BEAM VARIABLES. /AUTHOR/
