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.
