Oct 19, 2017· Main Reinforcements bars we provide in the shorter span of the slabs and the bars will along the longer span of the slab.In the long span of the slab the steel we provide known as Distribution steel which doesn't help to carry any types of load and the only function to distribute the load or counter the shrinkage stresses. For your better understanding let's take this example.How to calculate Cutting length of rectangular stirrup in ...Oct 23, 2017· First, we calculate the length of the stirrup and then we add the length of the hook and at the last, we subtract the length of the bend in the stirrup. Length of X = Width – 2(Half the diameter of the bar) – 2(Clear cover). = 450 – 2(5) – 2(35). = 370 mm.How to Estimate Formworks of Columns, Beams, and GirdersJul 09, 2018· 'P' is the perimeter of the column you want to estimate, 'a' is the shorter side and 'b' is the longer side. The constant value 0.20 is the value to consider for the lapping of form joints. Perimeter = 2 ( a + b ) + 0.20 Perimeter = 2 ( 0.20 + 0.20 ) + 0.20 Perimeter = 1.00 meter. 2. Multiply the value of perimeter obtained by the height of the ...How to Estimate Beam Reinforcement The Right Way - A Civil ...An ordinary person can estimate reinforcement as a lump sum. I see many people estimate reinforcement as a percentage of concrete volume. Such as 2% or 1.5% of concrete volume. But as a construction professional you shouldn't estimate rebar quantity as a percent of concrete volume. You should estimate that as shown in the structural drawing.how to estimate rebar in columnRebar inner strength to concrete slabs and columns.
