I have actually been request by one of our fan a inquiry that exactly how much does #8 rebar load per foot ? so I thought why not create a considerable guide ~ above unit weight of deformed rebars. So if friend have any type of question about:-
weight of rebar every footsteel load calculation formulaweight of reinforcing barsunit weight of steelYou space at the right place then because I am going to explain everything related to unit weight.Reinforcement bars room estimated, procured and also paid by unit of weight i.e. In kilograms, pounds, tonnes etc. Through unit weight of deformed rebars we typical its load per unit length. The two common units supplied for record unit load of steel room kilogram per meter (kg/m) and pounds per feet (lb/ft).Here’s a table reflecting unit weight of reinforcing steel bars in kg/m;Bar No.Size (diameter) mmTheoretical weight (kg/m)#39.53 mm0.56#412.70 mm1.00#519.05 mm1.56#625.40 mm2.24#732.26 mm3.05#835.81 mm3.98#928.65 mm5.07#1032.26 mm6.42#1135.81 mm7.92#1238.10 mm8.93#1443.00 mm11.41#1650.80 mm15.88#1857.33 mm20.28#2063.50 mm24.82

In any construction project involving reinforcing bars, bar bending schedules are submitted by the Contractor together an calculation of the amount of rebar stating the cut length of bar, diameter and weight the the rebar. This bar bending schedules room checked and also verified by the engineer at site for inclusion in IPC that the Contractor i m sorry is then paid by the Employer. 

Steel weight Calculation Formula

You can have heard or read around the formula as follows:Unit load of stole = d*d/162.28 (kg/m)Although this formula gives you a an extremely close approximation of the unit weight of rebar, but this will certainly never provide you the precise value of the stole unit weight.So what to do?You need to refer the stole manufacturer’s hand-operated wherein the unit load of the stole bars is quoted.

Derivation that Rebar Unit load Formula D2/162.28 Unit weight of stole = D2 / 162.28Now this formula has been derived from the density of the stole rebar i beg your pardon is 7850 Kg/m3.D is the diameter that the rebar in mm.The an outcome of this formula would certainly be weight per length i.e. Kg every meter.If us multiply the thickness (ρ) with the cross-section area the the rebar us will gain the load per length of rebar.So;Ρ x A = (7850 kg/m3 ) x (π x D2)/4

= (7850 kg/m3 ) x (3.14 x D2)/4=6162.25 x D2 kg/m (where D is in meters)Well, mostly we have actually φ diameter of rebar in millimeters.So let’s say Dm is diameter in mm so in order to convert that right into meters we need to divide it by 1000.Thus;1 meter = 1000 millimeters=6162.25 x (Dm/1000)2 kg/m=6162.25 x (Dm/1000)2 kg/m=0.00616225 x Dm2Or= Dm2/(0.00616225)-1=Dm2/162.2783 in kg/mWhere Dm is dia that rebar in mm.So this formula is provided for approximate worth of unit load of steel in MKS system.Coming back to our main asked question.

How much does #8 rebar load per foot ?

How lot does #8 rebar weight per foot? now this demands weight per foot.So we have to derive the formula for FPS system.

We know that1 meters = 3.28084 feetSo ;Ρ = 7850 kg/m3

Can be composed asΡ = 7850 kg/(3.28084)3 feetΡ =222.287 kg /ftNow;Ρ x A = (222.287 kg/ft3 ) x (π x D2)/4Ρ x A = (222.287 kg/ft3 ) x (3.14 x D2)/4 kg/feet=174.495 D2 whereby D is in feetAs greatly we have dia the rebar in mm therefore to convert that in feet us need;1 foot = 304.80 mmLets to speak Dm is dia in mm soUsing Dm/304.80 in above equation=174.495 (Dm/304.8)2=0.001878 Dm2Or= Dm2  / (0.001878)-1

=Dm2/533Where Dm is dia the rebar in mm.Now we have the right to answer the above question.

Answer

Φ = #8Convert into mm(now in our local language we speak to # together ‘sutar’)So1 sutar = 1/8 x 25 mm
