Abstract
The ultimate behavior of high-strength concrete beams is studied with respect to their strength. Thirteen beams were analyzed and the results are presented herein. The variable parameters were the concrete's compressive strength, from 57 to 184 MPa and the amount of lateral torsional reinforcement, from 0.35 to 1.49%. The ultimate torsional strengths from tests were compared with those by this proposed theory and by the ACI code. As a consequence, The ultimate torsional strengths by this proposed theory show the better results than those by the ACI code.
