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)
