Why Bars are bent in Slab near at Support

Bent up bars: Are the main reinforcements bent at a suitable angle to act as shear reinforcements.

Reinforcements are bent up to the supports/ends where greater compressive force occurs.

Bars Are Bend Near At Support To:

1- To resist shear force .

2-To resist (NBM) adjacent at supports.

3- To increment the strength of RCC in  slab.

4- Bent Up bar can abate the amount of steel.

5- Bent up bars in slab is more strong form normal slab.

6- Bent up bars sufficiently increase the deformation capacity of slabs as compared to those not having bars bent.

7- By extending bars up to supports, we can also lower the risk of brittle failure due to higher compressive stresses causing the structure to collapse.
