BENDING AND TORSION OF REINFORCED CONCRETE BEAMS

COMBINED BENDING AND TORSION TESTS WERE CARRIED OUT ON 55 RECTANGULAR CONCRETE BEAMS TO STUDY THE INFLUENCE OF CONCRETE STRENGTH, REINFORCEMENT AND THE INTENSITY OF APPLIED BENDING MOMENT ON THEIR TORSIONAL BEHAVIOR AND STRENGTH. TWO SERIES CONTAINED ONLY LONGITUDINAL REINFORCEMENT AND STIRRUPS INCLINED AT 45 DEG. AND 6 SERIES CONTAINED LONGITUDINAL REINFORCEMENT AND VERTICAL STIRRUPS. THE INTENSITY OF APPLIED BENDING MOMENT HAD LITTLE EFFECT ON THE INITIAL TORSIONAL STIFFNESS OF THE BEAMS OR ON THE TORQUE AT WHICH DIAGONAL CRACKING STARTED. A THEORY IS OUTLINED FOR DETERMINING THE MODE OF FAILURE AND ULTIMATE STRENGTH UNDER BENDING AND TORSION AND THIS IS COMPARED WITH THE RESULTS OF THESE TESTS AND THOSE OF OTHER INVESTIGATORS. /RRL/A/
