How do you calculate the number of bars needed?
The quantity is done in two steps.
- (Calculation of Bars No’s) First, calculate the number of bars required (main and distribution both). FORMULA = (Total length – Clear cover)/center to center spacing + 1. Main bar = (5000 – (25+25))/100 + 1.
- (Cutting length) MAIN BAR: FORMULA = (L) + (2 x Ld) + (1 x 0.42D) – (2 x 1d)
How do you calculate the area of a steel bar?
How to Steel Bar Calculation (Weight)
- Area of Bars = 10 x 10 = 100 mm = 100x 10-6 m2 (0.00010 m2)
- Weight of Steel Bar = (0.0001 m2 ) X 1 m. X 7850 kg/ m3
- Area of Reinforcement = (π/4) x 102 = 78.5 mm = 78.5 x 10-6 m2 (0.0000785 m2)
- Weight of Reinforcement = (0.0000785 m2 ) X 1 m. X 7850 kg/ m3
What is the length of one steel bar?
TMT Rebars are supplied in U bent or straight rods. Length of the TMT Bars are 40 feet. In most cases civil engineers, contracts recommend to buy TMT Bars in pieces, bundles or in tons.
How do you calculate 10mm steel?
10mm Steel rod weight per metre in kg Calculating 10mm rod weight per metre we use the formula D^2L/162, if dia of steel is equal to 10mm, length of a steel rod 1 metre then 10mm rod weight per metre = (10×10×1)/162 =0.617 kgs, so 10mm rod weight per meter is 0.617 kgs.
How much steel is required for slab?
Thumb rule for Steel required for RCC slab is 80 kgs/m3, then quantity of steel required for 100 sq ft ( 0.944 m3) rcc slab is equal to = 80 × 0.944 = 75.5 Kgs. Ans. :- 75.5 Kgs steel quantity are required for 100 sq ft 4 inch thick rcc roof slab.

What is the standard length of 12mm steel bar?
How do you calculate steel length?
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 many tons is 12mm rebar?
93 lengths of 12mm reinforcement bar makes 1 ton.
What is the weight in kg per meter length for 12 mm diameter steel bar?
Weight of steel bars per meter – Weight of steel bars formula
Diameter of bars in millimeter | Weight of bars in kilogram |
---|---|
10 mm | 0.62 kg/meter |
12 mm | 0.89 kg/meter |
16 mm | 1.58 kg/meter |
20 mm | 2.469 kg/meter |
How big is a 12 inch Rebar bar?
Often used in highway bridges, docks, parking structures and other large, concrete-based buildings requiring superior reinforcement, its metric equivalent or “soft size” is #40. The physical characteristics of #12 rebar are as follows: Weight per unit length: 6.424 pounds per foot.
What kind of work can number 12 rebar do?
Being fairly wide and heavy, #12 rebar lies in the high end of this spectrum, making it well suited to demanding, large-scale projects that require a significant degree of stability and support.
Which is longer a 16 inch bar or an 18 inch bar?
Compared to a 16-inch bar, the 18-inch bar would obviously have a longer cut length. However, the chain also has more distance to travel away from the engine. So running at 16-inches has less length, but more kick. You get the picture. Checking manufacturer recommendations is also an important step if you’re changing chainsaw components.
Do you need to change the chain on your bar?
If you increase (or decrease) the length of your bar, you will definitely need a new chain. This is pretty straight forward, if the bar gets longer, you’ll need a longer chain to wrap around it. In addition, you may need to replace your sprocket.
