Report on Torsion in Structural Concrete
Also Known As:
ACI 445.1R-12 is a standard report that provides a comprehensive overview of the effects of torsion on structural concrete members. The report begins by summarizing the history of torsion in structural concrete, including the development of various theories and models. It highlights the importance of considering equilibrium and compatibility conditions, as well as the constitutive relationships of materials, in the analysis of torsion in reinforced concrete.
The report also discusses the behavior of members subjected to torsion combined with bending moment, axial load, and shear. Design issues such as compatibility torsion, spandrel beams, torsional limit design, open sections, and size effects are addressed. Additionally, the report provides detailed guidance on the requirements for transverse and longitudinal reinforcement in torsional members, with step-by-step design examples using ACI, European, and Canadian standards.
