HIGH STRENGTH BOLT SHEAR CONNECTORS-PUSHOUT TESTS
STATIC PUSHOUT TESTS ARE PRESENTED OF CONCRETE-STEEL SPECIMENS USING HIGH STRENGTH BOLTS AS SHEAR CONNECTORS. THE BOLTS WERE EMBEDDED IN NORMAL WEIGHT CONCRETE AND PRETENSIONED BY THE TURN-OF-NUT METHOD AFTER THE CONCRETE HAD AGED 28 DAYS. THE LENGTH OF BOLT EMBEDDED WAS 4 IN. (10.16 CM) WITHIN A 6 IN. (15.24 CM) SLAB. STANDARD STEEL WASHERS WERE SPOT WELDED UNDER THE HEADS OF THE BOLTS PRIOR TO INSTALLATION. TWELVE SPECIMENS WERE TESTED, FOUR EACH WITH BOLT DIAMETERS OF 1/2, 5/8, AND 3/4 IN. (1.27, 1.59, AND 1.90 CM). TEST RESULTS SHOW VERY LITTLE SLIP BETWEEN THE SLAB AND STEEL BEAM UNTIL FRICTION IS OVERCOME. THE BOLTS EXHIBITED A GREATER USEFUL CAPACITY AND ULTIMATE STRENGTH THAN COMPARABLE STUDS. /AUTHOR/
