w₁ = 0.6 - 0.4 k ≥ 0.4 k = M_min/ M_max (positive for double curvature, negative for single curvature) M_fy ? Moment M_fx and M_fy should consider P-Δ effect (frame factor), if P-d (member factor) has been considered, U_1x and U_1y should be 1.0

w₂ = 4 M_max / [M_max² + 4 M_a² + 7 M_b² + 4 M_c² ]^0.5 <= 2.5 M_max - maximum factored bending moment M_a - factored bending moment at one-quarter point M_b - factored bending moment at midpoint M_c - factored bending moment at three-quarter point
