Reinforcement steel requirement for R.C.C Elements

Reinforcement  steel requirement for R.C.C Foundation / Footing, Pillar, Beam and Slab is  not same . Steel requirement of  these R.C.C elements in Residential Building is not same as that of Steel requirement in Commercial Building . So I can give the minnumm steel requirement and maximum steel requirement .

(1) Steel requirement for an R.C.C Foundation = 56 to 89kg for one Cum of Concrete .

(2) Steel requirement for an R.C.C Pillar/ Column = 115kg to 144kg for one Cum of Concrete . Cross section area of steel in an R.C.C Pillar should be within 0.8% to 6% of the Cross Section area of  a Pillar .

(3) Steel requirement for an R.C.C Beam = 108kg to 125 kg for one Cum of Concrete . Cross section area of steel in a Beam should always be more than 0.15% of the total Cross Section area of Beam

(4) Steel requirement for an R.C.C  Slab = 56kg to 89kg for one Cum of Concrete .Cross section area of steel in a Beam should always be more than 0.15% of the total Cross Section area of Beam.

(5) Steel requirement for an R.C.C  Retaining wall  is  based on earth / filling material to be retained the Hight of wall , Thickness of wall will be decided . Steel requirement will also depend on these factors .

(6) Steel requirement for an R.C.C  wall of an over head  Water storage tank .

Steel requirement will depending on the quantity of water to be stored and height of tank  from ground level . Wind effect to be considered to finalize e the design .

(7) Steel requirement for an R.C.C  wall of a Water storage tank below ground level .

Steel requirement for this tank will be less than that of an over head tank .

All these data is derived from the Residential, Commercial and Industrial projects  . some data about the consumption of steel from seniors including Structural Engineers, Senior Planning Engineer and  Quantity surveyor . In every project  verified and up dated it . The minimum and maximum quantity of steel mentioned above  is for Residential buildings , Commercial buildings & Industrial Buildings .
