How do you calculate the number of bars?
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)

What is the length of 16mm steel bar?
16mm steel bar weight:- 16mm steel bar supplied in U bent or straight rods, length of 16mm steel bar is 40 feet or 12meter and 16mm steel bar weight is 1.580 kgs/m, 0.480 kgs/foot, 18.96 kgs/piece and 56.889 kgs/bundle.
How do you calculate steel bars on a beam?
Calculate Steel quantity in beam as 2% of volume of concrete = 0.02× 7850× 5.29= 830 kg:- according to using Thumb Rule Steel quantity required in RCC beam should be 2% of total volume of concrete, here steel density = 7850 kg/m3, so quantity of steel in beam = 0.02× 7850× 5.29 = 830 kg.
How do you calculate steel?
STEEL QUANTITY:
- Weight of bar in kg/meter should be calculated as (d2 ÷ 162) where’d’ is the diameter of bar in mm.
- ‘L’ for column main steel in footing should be considered as minimum 30cm/as specified.
- For bent up bar add 0.42d in straight length of bar where’d’ is the clear depth of beam/slab.
What is the length of straight bar?
The length of the straight portion of a bar beyond the end of the hook should be at least four times the diameter. Note: The anchorage value of standard bend shall be considered as 4 times the diameter of the bar for each 45o bend subject to a maximum value of 16 times the diameter of the bar.
How do you find the diameter of rebar?
You can multiply the bar size by 1/8 to get the nominal diameter in inches. For example, #8 rebar = 8/8 inches (or 1 inch) in diameter. Common measurements indicate the weight, nominal area, and nominal diameter.
What is T10 rebar?
T10 Rebar – 10mm High Tensile Reinforcement Bar.
How are bar schedules calculated?
Example of Beam Reinforcement Calculation:
- Length of B1 = clear distance between walls + 2 x width of walls – 2 x bar cover + 2 x bend length.
- Length of bar B2: A + B + C = 4000 + 2 x 230 – 2 x 40 + (1.414xH – H)
- B2 = 4000 + 2 x 230 – 2 x 40 + (1.414×334 – 334) = 4518.3 = 4520mm.
How do you calculate column steel bars?
No of vertical bars = 6 nos. the diameter of the vertical bar = 16 mm. Diameter of stirrup = 8 mm.
HOW TO CALCULATE THE QUANTITY OF STEEL IN COLUMN (BBS)
| SIDE A | SIDE B |
|---|---|
| A =500 – 2 Side clear cover A = 500 – 2 x clear cover A = 500 – 2 x 40 A = 500 – 80 A = 420 mm | B =400 – 2 x Top & Bottom cover B = 400 – 2 x clear cover B = 400 – 2 x 40 B = 400 – 80 B = 320 mm |
How do you calculate the number of steel bars in a slab?
Steel Quantity Calculation
Formula = (total length – clear cover)/center to center spacing + 1 main bar, = (5000 – (25+25))/100 + 1, = 4950 divided by 100 + 1, = 51 bars., distribution bar = (2000 – (25+25))/125 + 1, = 1950 divided by 125 + 1, = 17 bars.
How do you measure bar spacing?
Minimum spacing between two bars can be taken as approximately 50–75 mm. According to cl. 26.5. 1.5 of IS 456, the maximum spacing of the stirrups = 0.75 d = 0.75 (450) = 337.5 mm = 300 mm (say).

How do you calculate lap length of a steel bar?
Normally, lapping position is at where near the minimum shear force is acting. Normally lap length is 50D meaning 50 times the bar diameter if both bars are of same diameter. When lapping two bars of different diameters, the lap length is considered as 50 times the smaller diameter.
