Section 11.3.10.3 Reinforcement for Torsion

Transverse reinforcement due to torsion calculated as per equation 11-17:

\frac{A_{s t}}{s} = \frac{T_{f} t a n θ}{\emptyset_{s} {2 A}_{o} f_{y s}}

where

A₀	=	the area enclosed by shear flow path, 0.85 A_oh
A_oh	=	the area enclosed by centerline of exterior closed transverse torsion reinforcement Area a bounded by stirrups
