Cranked bars / Bent up bars are provided on top of the reinforcement to resist negative bending moment/Hogging at the supports of the slab. To resist the shear force at the supports. To reduce the risk of a brittle failure of slab-column connection.
Where should crank be in slab?
Bent-up bars or known as Crank bars. We provide in the ends on the top of the slab or in the top of the mid supports (if any type of mid-support is present) to counter the negative moment called (Hogging), which produces at that sections of the slabs and beams.
What is the purpose of cranking?
A crank is an arm attached at a right angle to a rotating shaft by which circular motion is imparted to or received from the shaft. When combined with a connecting rod, it can be used to convert circular motion into reciprocating motion, or vice versa.
