Why bent up bars provided in R.C.C slab
Answers were Sorted based on User's Feedback
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!
