EFFECT OF ANCHORAGE EFFICIENCY OF LATERAL REINFORCEMENT ON THE TORSIONAL STRENGTH OF REINFORCED CONCRETE BEAMS

TWO METHODS OF ANCHORAGE OF LATERAL REINFORCEMENT WITH LONGITUDINAL REINFORCEMENT IN REINFORCED CONCRETE BEAMS, NAMELY EITHER TIED OR WELDED TO EACH OTHER, AND THEIR EFFECTS ON THE CONTRIBUTION OF THE REINFORCEMENT TOWARD THE ULTIMATE TORSIONAL STRENGTH OF THE BEAMS ARE DISCUSSED. EXPERIMENTAL RESULTS ARE PRESENTED WHICH SHOW THE SUPERIORITY OF WELDING THE LATERAL REINFORCEMENT TO THE LONGITUDINAL REINFORCEMENT OVER THE OTHER METHOD. LEVELS OF STRAIN IN THE LATERAL STEEL ARE SHOWN TO BE AT OR ABOVE YIELD STRAINS IN WELDED BEAMS, BUT BELOW YIELD STRAINS IN TIED BEAMS. A MODIFIED EXPRESSION FOR THE ULTIMATE TORSIONAL STRENGTH OF WELDED RECTANGULAR REINFORCED CONCRETE BEAMS IS SUGGESTED BASED ON THESE FINDINGS. /AUTHOR/
