STATIC AND FATIGUE BEHAVIOR OF CONTINUOUS COMPOSITE BEAMS WITH HIGH STRENGTH BOLTS AS SHEAR CONNECTORS

SOME ASPECTS ARE STUDIED OF FATIGUE AND STATIC BEHAVIOR OF CONTINUOUS COMPOSITE BEAMS USING 3/4 INCH HIGH-STRENGTH BOLTS AS SHEAR CONNECTORS. TESTED IN THIS PHASE OF THE PROGRAM WERE: (1) NINE PUSHOUT SPECIMENS SUBJECTED TO REPEATED LOADING WITH VARYING LOAD RANGES, (2) TWO FULL SCALE CONTINUOUS COMPOSITE MEMBERS, ONE WITH AND ONE WITHOUT SHEAR CONNECTORS OVER THEIR NEGATIVE MOMENT REGIONS, LOADED BOTH DYNAMICALLY AND STATICALLY, (3) TWO COMPANION COMPRESSION PUSHOUT SPECIMENS, ONE LOADED DYNAMICALLY AND THEN SUBJECTED TO A FINAL STATIC LOADING, ONE DIRECTLY SUBJECTED TO THE DESTRUCTIVE STATIC LOADING, AND (4) TWO COMPANION TENSION PUSHOUT SPECIMENS, BOTH LOADED STATICALLY UNTIL FAILURE. LOAD-SLIP AND FATIGUE CHARACTERISTICS OF THE BOLTED CONNECTION WERE INVESTIGATED THROUGH THE TESTING OF THE PUSHOUT SPECIMENS. LOAD-DEFLECTION, LOAD-SLIP, CYCLE-SLIP CURVES, STRAIN PROFILES, SLIP DISTRIBUTION AND LOAD-REACTION CURVES WERE USED IN THE INVESTIGATION OF THE FULL SCALE COMPOSITE MEMBERS. PREDICTED BEHAVIOR WAS COMPARED WITH THE EXPERIMENTAL BEHAVIOR AND THE CRACKING PATTERNS WERE ANALYZED IN DETAIL. ALSO THE MEMBERS WITH AND WITHOUT CONNECTORS WERE COMPARED CONCERNING THE NEGATIVE MOMENT REGION. /AUTHOR/
