Minimum Reinforcement in Slabs and Beams<\/strong><\/h2>\n\n\n\n

Reinforced Concrete is a concrete in which steel is\nembedded in such a manner that the two materials act together in resisting\nforces. The reinforcing steel rods, bars, or mesh absorbs the tensile, shear,\nand sometimes the compressive stresses in a concrete structure.<\/p>\n\n\n\n

When the concrete sets and hardens around the bars, we\nget a new composite material, reinforced concrete (also called reinforced\ncement concrete or RCC), that works well in either tension or compression: the\nconcrete resists squeezing (provides the compressive strength), while the steel\nresists bending and stretching.<\/p>\n\n\n\n

  1. Minimum distribution reinforcement steel (for TOR Steel) shall be 0.12% of the overall sectional area. i,e., 0.12 x 100cm x D cm=0.12D Sq.cm for 1 m width of slab where D is the overall depth of slab. Minimum reinforcement is ensured in slab (in both directions) to take care of shrinkage, thermal movements and distribution of loads etc.<\/li>
  2. Minimum reinforcement steel is provided subject to the condition that maximum permissible spacing shall be 5 times the effective depth or 45 cms whichever is less.<\/li>
  3. For providing main reinforcement steel, the criteria of max spacing is 3 times the effective depth or 45 cms whichever is smaller<\/li>
  4. Maximum diameter of bar in slab will not exceed 1\/8″ of total thickness of slab and minimum diameter of bar is 6 mm<\/li>
  5. Maximum reinforcement in slab is restricted 1 to 2 % of gross sectional area.<\/li>
  6. Minimum Thickness of RCC Slabs and Beams Slabs <\/li>
  7. Simply supported slab spanning in one direction = Effective Length of Slab \/30<\/li>
  8. Simply supported Slabs Spanning in Two Directions = Effective Length of Slab \/35<\/li>
  9. Continuous Slab Spanning one Direction = Effective Length of Slab \/35<\/li>
  10. Continuous Slab Spanning Two Directions = Effective Length of Slab \/40<\/li>
  11. Cantilever Slab = Effective Length of Slab \/12<\/li><\/ol>\n\n\n\n
