Area of reinforcement per meter " StructX (2014-2024) There are useful tables available which can be used to quickly look up the area of reinforcement of a structural element for a given bar diameter and number of bars. Imperial. The table lists bar spacing from 50 to 300 mm, number of bars per meter, bar diameters from 5 to 40 mm, and the corresponding cross-sectional area of reinforcement in mm2/m for each combination of spacing and diameter. Cross sectional area = A = (π D 2) / 4. 996 kilograms per meter) Nominal diameter: 0. S. (sq. Estimate number of 12mm bars needed for a slab with 5m x 4m dimensions and 150mm thickness. The unit weight of steel is generally measured in kilogram per cubic meter is 7850kg/m3, measured in kilo-Newton per cubic meter is 78. Solution, Area of Slab = 5 x 3 = 15 meter Square = 161. biqno csu uweqj bvnr kbfb vick fziwl wxlls kjvyrzyv fsux
