N = [(Length of Y-direction footing – 2 x cover)/spacing of steel bar] + 1

  1. A = 1200 mm length in X-direction.
  2. B = 1200 mm length in Y-direction.
  3. C = 50 mm cover of footing.
  4. a = 150 mm spacing in X-direction bar.
  5. b = 200 mm spacing in Y-direction bar.
  6. d = 450 mm depth of footing.
  7. D = Length of 90′ bend.
