Beam Shear Stress
Allowable beam shear stress on the gross section must conform to Clause 3.2.4-2 of the API code:
Fv = 0.4·Fy
The maximum applied beam shear stress is per Eqn 3.2.4-1:
fv = V / 0.5 A
Torsional Shear Stress
Allowable torsional shear stress per Eqn. 3.2.4-4:
Fvt = 0.4·Fy
Fvt is the maximum torsional shear stress per Clause 3.2.4-3 of the API code.
