D1.J.2.5 Bending Stress

The allowable bending stress for tension and compression for a symmetrical member loaded in the plane of its minor axis, as given in Clause 3.2.3 of the API code, is:

  1. When D/t ≤ 1,500/Fy (Imperial Units),

    Fb = 0.75Fy

  2. When 1,500/Fy < D/t ≤ 3,000/Fy (Imperial Units),

    Fb = [0.84 - 1.74 FyD/(Et)]Fy

  3. When 3,000/Fy < D/t ≤ 300 (Imperial Units),

    Fb = [0.72 - 0.58 FyD/(Et)]Fy
