CFVR4056 - Reinforced concrete design according to GB 50010 2010 Chinese code
Combined shear and torsion design.
A concrete cantilever beam with T shape section and shear & torsion reinforcement is subjected to a vertical load and torsion moment at free end.
Determine the area per unit length of torsional transverse reinforcement, total area of torsional longitudinal reinforcement and the area per unit length of shear reinforcement according to GB 50010-2010.
