THE FLEXURAL STRENGTH OF CONCRETE BEAMS REINFORCED WITH VERY HIGH-STRENGTH STEEL

AN INVESTIGATION IS MADE INTO THE ULTIMATE LOAD BEHAVIOR OF CONCRETE BEAMS REINFORCED WITH DEFORMED BARS WITH PROOF STRENGTHS VARYING BETWEEN 414N PER SQ. MM AND 966N PER SQ. MM (60,000 AND 14,000 LB PER SQ. IN.) A METHOD BY WHICH THE ULTIMATE BENDING MOMENT CAN BE CALCULATED IS SHOWN TO AGREE REASONABLY WITH THE EXPERIMENTAL RESULTS. IT IS SHOWN THAT STEEL WITH A YIELD POINT OF UP TO 552 N PER SQ. MM (80,000 LB PER SQ. IN.) CAN OFFER WORTHWHILE ECONOMIC ADVANTAGES AND THAT THE CRACK WIDTHS ASSOCIATED WITH THE HIGHER WORKING STRESSES ARE TOLERABLE FOR NORMAL EXPOSURE. /RRL/(A)
