END ANCHORAGE OF HIGH STRENGTH STEEL REINFORCING BARS

PULLOUT TESTS WERE CONDUCTED TO EVALUATE END ANCHORAGE FOR DEFORMED BARS WITH A NOMINAL YIELD STRENGTH OF 60,000 PSI (4220 KG/SQ. CM.) EMBEDDED TO CONDITIONS APPROXIMATING THOSE IN A SEMI-INFINITE MEDIUM. THREE SIZES OF BARS, NO 4 (1.3 CM DIAMETER), NO 7 (2.2 CM.), AND NO 11 (3.5 CM.) AND THREE TYPES OF ANCHORS, STRAIGHT, RIGHT ANGLE HOOK AND SEMICIRCULAR HOOK, WERE STUDIED. FOR A GIVEN DISPLACEMENT AT THE LOADED END, THE AVERAGE BOND STRESS INCREASES AND THE BAR STRESS DECREASES WITH INCREASE IN BAR DIAMETER. FURTHERMORE, THE EFFECTIVENESS OF AN ANCHOR IS A DIRECT FUNCTION OF THE CONCRETE STRENGTH. AVERAGE BOND STRESS APPEARS TO BE THE MOST USEFUL DESIGN CRITERION. /AUTHOR/
