[ K = M / (b d^2 f_cu) = 320 \times 10^6 / (1000 \times 440^2 \times 40) = 0.041 ] Since K < 0.156 → singly reinforced. [ z = d [0.5 + \sqrt0.25 – K/0.9] = 440 [0.5 + \sqrt0.25 – 0.041/0.9] = 418 \text mm ] [ A_s = M / (0.87 f_y z) = 320 \times 10^6 / (0.87 \times 460 \times 418) = 1916 \text mm^2/m ] Provide T20 @ 150 mm c/c (2094 mm²/m) .
