Abstract
Torsion tests on high strength concrete hollow beams have revealed some ductile behavior. However, this ductile behavior only occurs for a narrow interval of the torsional reinforcement ratio. Tests have shown that a torsion plastic hinge can be formed. Furthermore, this torsion plastic hinge is concentrated in a small length of the longitudinal axis of the beams. In this paper, the authors show that plastic models are possible for beams under torsion. A torsion plastic hinge at the failure cross section can be assumed. This paper also shows that torsional ductility becomes more difficult as the concrete strength increases.
