LATERAL INSTABILITY OF REINFORCED CONCRETE BEAMS UNDER UNIFORM BENDING MOMENTS

THE LATERAL STABILITY CONDITIONS FOR A SINGLE SPAN SLENDER REINFORCED CONCRETE BEAM UNDER UNIFORM BENDING MOMENT ARE EXAMINED. A METHOD FOR PREDICTING THE CRITICAL BENDING MOMENT IS SUGGESTED, BASED ON THE LATERAL BENDING AND TORSIONAL RIGIDITIES AND, IN THE CASE OF DOUBLY REINFORCED BEAMS, ON THE WARPING RIGIDITY. IT IS SHOWN THAT THESE RIGIDITIES DEPEND NOT ONLY ON THE OVER-ALL DIMENSIONS OF THE CROSS SECTION BUT ALSO ON THE PERCENTAGE OF STEEL, THE NUMBER, TYPE AND SIZE OF STIRRUPS, AND THE STATE OF STRESS. EXPERIMENTAL RESULTS ARE DESCRIBED WHICH SUPPORT THE PROPOSED THEORY. THESE RESULTS ARE THEN COMPARED WITH STANDARD DESIGN RECOMMENDATIONS. /AUTHOR/
