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 .
