Torsion of Reinforced Concrete -A Historical Overview
The story of torsion of reinforced concrete must start with the French professor, C. L. Navier. In his landmark book (Navier, 1826) he rigorously derived the first rational theory for...

Overview of Structural Behavior of Members Subjected to Torsion
The torsion strength of concrete beams depends on many factors, such as the amount of reinforcement, the volumetric ratios of longitudinal and transverse steel bars, the concrete strength,...

Advances in Analytical Modeling of Torsional Members
The basic formula for calculating the torsional strength of reinforced concrete members was developed by Rausch (1929) using the space truss concept. Unfortunately, Rausch's equation may...
