Title: Strength of Reinforced Concrete Beams
With Web Reinforcement
ln Combined Torsion, Shear, and Bending
Author(s): D. L. Osburn, B. Mayoglou, and Alan H. Mattock
Publication: Journal Proceedings
Appears on pages(s): 31-41
Keywords: beams (structural) ; bending; reinforced concrete; research; shear; stiffness; torsion;web reinforcement.
Abstract:Tests in combined torsion, shear, and bending are reported for 22 rectangular and r-shaped beams designed according to proposals contained in the paper " How to Design for Torsion." The test results confirm that both these design proposals, and those contained in "Tentative Recommendations for the Design of Reinforced Concrete Members to Resist Torsion" by ACI Committee 438, Torsion, are reasonably conservative. It was also found that the torsional stiffness at service load, of a reinforced concrete beam with web reinforcement subject to combined torsion, shear, and bending, is approximately one-half the torsional stiffness of the untracked section.
