How do you calculate reinforcement quantity?
Method-2 : Reinforcement Estimation (Accurate Method):
- Calculation:
- Bar 1:
- Cutting Length = 4380 mm.
- Bar 2:
- Cutting Length = (2×200) + (4380) – (2 x 20 x 2) = 4700 mm.
- Bar 3:
- Cutting Length:
- No. of Stirrups: (4000/180) + 1 = 23.22 = 24.
How do you find the quantity of steel?
This can be done by multiplying cross section area of steel by its total length by density of steel which 7850 kg/m3. Total steel quantity of column equal to the sum of both main and stirrup steels.
How are reinforcement bars calculated?
Layout of Rebar for Concrete Slabs
- Convert your longitude measurement into inches: 15 feet x 12 inches per foot = 180 inches.
- Divide your result by the spacing measurement: 180 in / 14 in = 12.87 (round up to 13)
- Add one rebar to your result: 13 + 1 = 14.
How do you convert reinforcement to KG?
If we put 1 meter length for each diameter of steel bar in the formula then we will get the unit weight.
- 6 mm ø bar = 6² x 1/162 = 0.222 kg/m.
- 8 mm ø bar = 8² x 1/162 = 0.395 kg/m.
- 10mm ø bar = 10² x 1/162 = 0.617 kg/m.
- 12mm ø bar = 12² x 1/162 = 0.888 kg/m.
- 16mm ø bar = 16² x 1/162 = 1.580 kg/m.
How do you calculate reinforcement quantity in a beam?
Calculate Steel quantity required for beam as 2\% of volume of concrete = 0.02× 7850× 1= 157kg:- according to using Thumb Rule Steel quantity required for RCC beam should be 2\% of total volume of concrete, here steel density = 7850 kg/m3, so quantity of steel in 1m3 of concrete beam = 0.02× 7850× 1= 157kg, so, therefore …
How do you calculate steel per square meter?
Thumb rule for Steel required for RCC slab is 80 kgs/m3, then quantity of steel required for 100 sq ft ( 1.416 m3) rcc slab is equal to = 80 × 1.416 = 113.3 Kgs.
How do you calculate quantity drawing?
Steel Quantity Calculation (Cutting length) main bar: formula = (l) + (2 x ld) + (1 x 0.42d) – (2 x 1d), where l = clear span of the slab, ld = development length which is 40 d (where d is diameter of bar), 0.42d = inclined length (bend length), 1d = 45° bends (d is diameter of bar) first calculate the length of “d“.
How do you calculate rebar weight in kg?
W= (D2/162.28)* L Where ‘D’ and ‘L’ are the diameter and the length of the rebar respectively. Take the value of diameter in terms of millimeter and length in terms of meters. You will get the results in kilograms (Kg). After dividing the results with the actual length of rebar you can get the weight per meter run.
What is the weight of TMT bars?
| TMT Bar Size (In mm) | TMT Bar weight in kg/m |
|---|---|
| Shyam Steel flexiSTRONG TMT Bar 16 mm | 1.580 |
| Shyam Steel flexiSTRONG TMT Bar 20 mm | 2.470 |
| Shyam Steel flexiSTRONG TMT Bar 25 mm | 3.850 |
| Shyam Steel flexiSTRONG TMT Bar 28 mm | 4.830 |
How do you calculate the weight of a reinforcement net?
If the same size of bars is used in both directions then you can sum up both quantity of the bars Convert that length into kilograms or Tons. This can be done by multiplying cross section area of steel by its total length by density of steel which 7850 kg/m 3 The above calculation procedure is for single reinforcing net.
How do you calculate the number of reinforcement bars in concrete?
Let us take an example and estimate the quantity of reinforcement in method, Suppose the spacing of stirrups is 150 c/c and the length along which they are placed is 6800 mm, we can find the number of bars by the formula below [ Length / Spacing] + 1 = number of bars [ 6800 / 150] + 1 = 46.33 In this case, we always round up.
How to calculate main and shrinkage of steel bars?
Main Steel Bars No. of bars= (Slab length (L)/spacing)+1 Equation 1 Shrinkage and Temperature Steel Bars No. of bars= (Slab length (S)/spacing)+1 Equation 2 In equation 1, center to center spacing of main reinforcement steel bars are used and shrinkage and temperature bar spacing is used in equation 2. 3.
How to compute number of steel bars in a slab?
Compute number of steel bars. Main Steel Bars No. of bars= (Slab length (L)/spacing)+1 Equation 1 Shrinkage and Temperature Steel Bars No. of bars= (Slab length (S)/spacing)+1 Equation 2 In equation 1, center to center spacing of main reinforcement steel bars are used and shrinkage and temperature bar spacing is used in equation 2.
