WebUnit Weight Of Steel: To prepare BBS at site you need to calculate the weight of steel first. The weight of bars is calculated by the following formula. W = d²L/162. Where W = Weight of bars. L = Length of bars in meter. d = Diameter of the bar. Example: Calculate the weight of 20 meters long 16 mm ø bar. W = 16² x 20/162 = 32 kg. Webuniformly spaced in outer portions of footing. e) Check development length: Find required development length, l d, in tension from handout or from equations in ACI 25.4. l d must be less than (L m – 2”) (end cover). If not possible, use more bars of smaller diameter.
