Answer / agha zafar

it is actually economization of material. normally, for
fixed ended beams positive (sagging) moments are present at
the mid span and negative (hogging) moments at the supports.
so bottom steel is required at the mid span and top steel
resists negative moments at the supports. a bent-up is
provided to take the steel on the top at supports as bottom
steel is not normally required at at the supports (only
nominal steel is sufficient). hope it'd help!

Answer / mustafa mohammed layeak

Bent up bars (Cranked bars) in slabs are provided to resist
the negative moment (Hogging BM) produced at supports
(beams).

Answer / b.baba

to resist the shear created at corner

Answer / srinivasan

to resist negative moment

Answer / adeel shahzad

To resist negative moment .

Answer / rajnish kumar

to prevent negative bending moment at corner

Answer / ritesh

These are main reinforcement bent up at suitable angle generally 45degree ,
these are only provided with shear reinforcement.

Answer / aabid

bent up bar required slab because shear force develop in the corner side so this develop shear force stopped so need for bent up bar required.

Answer / nikita rajput

To resist negative hogging moment at ends n provision from torsional moment

Answer / abhishek sabale

To prevent from lifting at corner edges due to torsional moments.
