D9.A.4.3 Design for Torsion
Torsion design for beam is optional. If the TORSION parameter value is 1.0, the program will design the assigned beam(s) for torsion. The program first checks whether extra reinforcement is needed for torsion or not. If additional reinforcement is needed, this additional pt is added to flexure pt and additional Pw is added to shear design Pw.
