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 strenth 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 capacityof 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.
