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 .

See More  Effect of varying percentages of steel on the moment of resistance of RCC Section

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 .
