Number of reinforcement bars Total reinforcement area Bar size no. of rebars Required reinforcement area Required reinforcement area: mm 2 Cross sectional area of number of bars (mm 2) BAR SIZE (mm) Number of bars 1 2 3
When installing a concrete slab or structure it is a good idea to add rebar, or reinforcing bar, to reinforce it and prevent it from cracking down the road. Using rebar as reinforcement adds considerable strength to concrete and reduces the overall slab thickness needed. Calculating the amount of bar needed can be done in a few simple steps.

We know a formula to calculate the weight of bar. That is D²L/162. Where, D= Diameter of bar in millimeter L= Length of bar in meter Now the question is what the 162 is. Let''s see. To calculate the weight of something else we often use the followi...
Main steel bars=No. of bars*cutting length*weight of the bar (/162) Equation 7 (/162) is the weight of a steel which is derived from steel volume times its density which is 7850 kg/m 3. Calculate Steel for Footing. Size of footing and its reinforcement details (bar size and spacing) shall be known. This can be achieved from design drawings.
Reinforcing steel EC2 does not cover the use of plain or mild steel reinforcement. Principles and rules are given for deformed bars, decoiled rods, welded fabric and lattice girders. There is no technical reason why other types of reinforcement should not be used. Relevant authoritative publications should be consulted when
Enter the required splice (overlap) of your bars. (inches) Enter the amount of bars for your footings. Enter a waste factor, if required (percentage) The Results. Amount of rebar needed in lineal feet. The amount the waste factor will add in lineal feet. Lineal feet of rebar plus the amount of waste. The amount of result 3 divided by 20. Number ...
the current published size extras for fabricated bars f r om a major rebar fabri c a t o r. Note that the size extra for #3 bars is per hundred pounds or 80 per ton more than for #4 bars. This shows that it is generally more economical to specify #4 rather than #3 bars for approx i mately equal areas of steel. Similar comparisons could
Canadian Rebar Weight Calculator Metric. Calculate the weight of Canadian rebar sizes in KG / Metre. Canadian Bar Sizes: 10M 15M 20M 25M 30M 35M 45M 55M Lineal Feet of Rebar: lin M: Results: Weight of Rebar in Kilograms: kg: Weight of Rebar in Pounds: lbs: Metric Bar .
Jan 13, 2015· Accurate calculation of reinforcement in the building plays an important role in the over all costing of the project. The estimation of the reinforcement is made from the drawings and bar bending the cases where there is no availability of drawings and schedules, the quantity is normally described in accordance with the requirements of the Standard method of measurement of .
Round Bar is a long, cylindrical metal bar stock that has many industrial and commercial applications. The most common application is shafts. Round Bar is available in many metal types including HotRolled Steel, ColdRolled Steel, Aluminum, Stainless Steel and more.
Mathematically, density is defined as mass divided by volume: ρ = m / V" Density is thus the necessary information to look for in the product data sheet to calculate the consumption in kg for an expected wet thickness. But be careful with the term "density" in product data sheets! Density or mixed density? The difference is crucial.
FIrst, find number of rods required for main reinforcement and distribution. Number of Required Bars Formula = (Length of slab / spacing) + 1. Number of Main Bars = Ly / spacing + 1 = (4000/150) + 1 = 27 nos. Number of Distribution Bars = Lx / spacing + 1 = 3000/150 + 1 = 21 nos. Step 2. Find cutting length of main bars and distribution bars
7: Reinforcement: Main Steel 100 dia. 120 mm c/c : i) Lower flight and landing: 10 : : : Kg : L = + (at toe) + + (hook) – 2 ...
The deformed Reinforcing Steel Bar is supplied in length of 9m or 12 m as common sizes. The steel bar diameter applied is different and accordingly the weight varies. We are listing theoretical unit weight list of commonly used wire gauge below for your reference.
Volume of Steel Bar () = Area of Steel Bar () X Length of Steel Bar (mtr) Since We are trying to calculate the unit weight of Steel Bar, the length of Steel Bar in the calculation would be 1 mtr or 1000 mm. Area of Steel Bar = ( X D^2)/4. Density of Steel Bar = 7850 Kgs/ = 7850/(1000X1000X1000) Cubic mm
What will be the formula to calculate the steel bar''s weight if the length of the bar is on the foot? You May Want to Read: Concrete Cover for Reinforcement Bar Types of Rebar Support in RCC Member. Calculating Weight of Steel Bars When Length is in Foot. Again, Weight = A x L x ρ = x D²/(4 x x ) x 222 = D²L/533. Where,
Weight of any material (Mass) = Volume X Density. If we are calculating the weight for standard steel bar as shown in the picture, then it hard to calculate the area because of the ridges. It can be done by Archimedes theory, We hope you have learned this in school level. Take a sample length of a steel bar (Ex. 1 meter)
Since We are trying to calculate the unit weight of Steel Bar, the length of Steel Bar in the calculation would be 1 mtr or 1000 mm. Area of Steel Bar = ( X D^2)/4 Density of Steel Bar = 7850 Kgs/ = 7850/(1000X1000X1000) Cubic mm
Oct 17, 2017· Weight = Volume x Density = x 7850 = kg. Ans.. Note: If you are calculating the weight of circular steel reinforcement bar than calculate its volume by using this formula (πD^2/4) and then just multiply by the density of steel which is 7850 kg/m^3. BY FORMULA: To calculate the weight of circular reinforcement bars etc.
Following Are The Steps To Calculate The Quantity Of Steel For RCC Slab: 1 Prepare a bar bending schedule in order to classify different shapes of bars (bent up bar, straight anchor bar, eos bar, curtail bar etc) and diameters.. 2 List down all the shapes of bars from the drawing.. 3 Count the number of bars of each of those shapes.. 4 Then calculate the cutting length of each of those bars.
Mar 10, 2018· Converting Different diameter reinforcement steel bar into Tons is very important. It assist in buying of Reinforcement because all reinforcement are being purchase in Tons. It also help you in evaluating the exact amount to be paid to the Iron Bender. Density = Mass/Volume Density of steel = 7900kg/m3 Length of steel = 12m (standard [.]
Weight of reinforcement in kg/m3. Bases Beams (lightly loaded) Beams Capping beams Columns (lightly loaded) Columns Ground beams Footings Pile Caps Plate slabs Rafts Retaining walls Ribbed floor slabs Slabs – one way Slabs – two way Stairs Tie beams Transfer slabs Walls – normal Walls – wind. 90130 100150 150300 135 110200 200450
Jan 12, 2019· First of all, Bar is any type of rebar which is used as a reinforcement in RCC. The bar may be a Mild Steel bar or HYSD bar or TMT Bar . Bar Bending Schedule is termed as "Calculation of the total Steel required for the construction of a building" We use steel to make concrete to be reinforced and for tension requirements.
