Calculate Steel Reinforcement and its quantity in Slab, Beams, Columns and Footing

RCC drawings so that you can find out the following values from the drawing :

Length of the element :
Cross section:
No of bars
Type of bars
Spacing between the bars.
Lap length ( horizontal/vertical)
Development length
Covers for footing/column/beam/slab.

2. Calculate the cutting length of the bars.
( total length – covers on bothside )+ development length.

3.Formula :
W = N*CL*U

W: Weight of reinforcement
N: No of bars
CL: cutting length
U:Unit weight

You can find out Unit weight from charts or from the formula :
U= D*D/162.
