छत में crank bars कितना लंम्बा दे...
Purpose of crank bars in slab
1.Cranks or bent-up bars are used to fight negative
bending moments at supports. These moments can cause failure if not handled right.
2. To resist shear force which is greater at
supports.
3. To reduce the risk of a brittle failure of
slab-beam & column connection.
4. To reduce the amount of steel used.
5. For the economization of materials.
Structural Integrity...
They make the slab stronger and more flexible, keeping the structure stable.
