How to work out the quantity of steel in beam

In this construction video tutorial, the renowned engineer S.L. Khan briefly explains the process for finding out the quantity of steel in beams. 

The calculation is made on the basis of the following dimensions :- 

The length of the beam is taken as 10 feet 

The depth of the beam is taken as 18 inches 

The dead hooks in main bars are taken as 9d 

The angle of bent up bars with horizontal lines is 45 degree 

To determine the quantity of steel for main bars, initially you have to find the total cut length of bars with the following formula :- 

= [10’ – 2(c.c.) + 2(hooks)] x Number of bars
