GENERAL POINTS FOR CALCULATIONS OF REINFORCEMENT:

A Vision To Clear Solutions.

1. For beam hook= (beam depth-both side covers)/2

for example if it is a 450mm depth beam then hook is (450-50)/2=200

where cover for beam is taken as 25 mm

2. For stirrups the hook=4d as per is codes but according to site conditions it is

50 mm per hook while doing bar bending schedule.

3. For slab the rod the crank length is l/5.

4. For beam the bottom extra is at l/6.

5. For slab the top extra extends till upto l/3.

6. For beam the top extra bar extends till l/3.

7. The column capitals extends tilll/4.

8. Where l is effective length of the beam. It is taken as center to center of the beam.

9. The crank length is 1.41d, where d is (depth of slab or beam- two side covers)

Component	Cover in mm
Slab	15
Beam	25
Column	40
Footing	50

Note: cover is given for the aggregates of concrete to pass through the reinforcement and to prevent the reinforcement from exposing to surface.

BINDING WIRE CONSUMPTION:

Binding wire used for tieing one tonnage reinforcement

6 to 7 kgs
