## How To Calculate Steel Quantity For RCC Beam, Column And Slab

Following are the steps to calculate the quantity of steel for RCC slab

1. Prepare a bar bending schedule in order to classify different shapes of bars (bent up bar, straight anchor bar, eos bar, curtail bar etc) and diameters.

2. List down all the shapes of bars from the drawing.

3. Count the number of bars of each of those shapes.

4. Then calculate the cutting length of each of those bars.

Cutting length of bar = (length of the member deduction for cover on both sides) + development length.

5. Then calculate the unit weight of each dia bars by the following formula:

W = d^2/162

Where d is the dia in mm and weight (w) in kg.

6. Then calculate weight of rebar

Weight of rebar= no of bars x cutting length x unit weight

7. Add all the weight to get the total steel quantity.

NOTE1. Minimum % of steel as per Indian standard are:

1. Beam (Teinsion reinforcement):

As = 0.85bd/fy  of gross cross-section area.

2. Slab – 0.12% of total area

3. Column – 0.8% of cs area

2. Maximum % steel as per Indian standard are:

• Beam – 4 % of cross-section area.

• Slab – 4% of cross-section area.

• column — 6% of cross-section area.

3. . Development Length is usually specified in the drawings, but if not thenyou can calculate it as,

D.L = Depth – 2 times cover

4. Binding wire = 10 grams per kg of reinforcement.

5. No. of stirrups = (length of member – 2 x cover ) / spacing + 1

#### About Admin 1. Super for civil work

2. What are safety observe during shuttering ? and
How to calculate the area of steel in slab ?

Plzz tell me..

3. please, make an example caculation so that we can clearly understand the calculation.

4. Plz illustrate with examples to understand. Thanks

5. Pls gv me example for calculation of steel.quantity on slab

6. Please provide checklist for slab checking, formwork, shuttering etc.

7. Is nice to be part of this group.

8. In reinforcement percentage calculation stirups are taken into the account or NOT

9. Plz give me example for calculation of steel
