Reasons for Providing Compression Reinforcement

Reduced sustained load deflections.
- Creep of concrete in compression zone.
- Transfer load to compression steel.
- Reduced stress in concrete.
- Less creep.
- Less sustained load deflection.
Effective of compression reinforcement on sustained load deflections.
Increased Ductility.
Effect of compression reinforcement on strength and ductility of under reinforced beams.
Change failure mode from compression to tension.
Eases in Fabrication.
- Use corner bars to hold & anchor stirrups.
