ACI Code Provisions for Torsion Design of Reinforced concrete Beams, A Need for Revision

Mohammad Najim Mahmood

Abstract:
This study summarizes the critical provisions specified by the ACI 318-05 (2005) code, that are used for the design of reinforced concrete beam under pure torsion. Some parameters have been considered like the beam size, material properties and their effect on the required torsional reinforcement. The main emphasis is to highlight the drawback of this latest ACI code's provisions for the design of reinforced concrete beam under pure torsion. It was found that, before cracking, the required torsional reinforcement for beam with higher concrete strength is more than that of weaker concrete when the beam undergoes the same factored torsion. After cracking the required torsional reinforcement is not affected by the concrete strength, while the code specified the permitted maximum factored torsion as a function of the concrete strength.
