Suppose we are using a steel bar Fe 500 and concert mix M25. The diameter of the bar will be 10 mm. By using the formula, the splice length of the steel bar will be 49 x 10 = 490 mm and if the bar is in tension zone and 39 x 10 = 390 mm if the bar is in the compression zone.
The Lapping length in tension (MS bar – mild steel bar) along with anchorage value is 58d. Therefore, after deducting the anchorage value, the lap length should be = 58d – 2*9d = 40d. (Here 9d = hook allowance up to 25 mm and k=2) Lap length for M20 concrete: Also Read: Importance of perfect lapping of steel bars in RCC construction works
13-01-2015· Calculation: Bar 1: b = 4000 + (2 x 230) – (2 x 40) = 4380 No bends, hence, no deductions Cutting Length = 4380 mm Bar 2: a = 200 b = 4000 + (2 x 230) – (2 x 40) = 4380 Deduction : (2 x dia x no. of bends) = 2 x 20 x 2 Cutting Length = (2x200) + (4380) – (2 x 20 x 2) = 4700 mm Bar 3: a = 230 – (2x40) = 140 c = 375 – (2x40) = 285 Cutting Length: (2A + 2C) + 24d = (2x 140 + 2x 285) + 24x8 = …
12-01-2019· It's a lengthy article, so brace yourself for atleast 10 minutes. Let's Get started. 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 ...

Do you think it's that simple formula (D 2 / 162.2) for steel weight calculation of a bar?. Nope… It's hard to find the exact weight of steel bars according to its area, it is advisable to refer the manufacturer's chart to calculate the weight of the steel bar.
At the time of bending the reinforced steel bar at some angles (degrees), owing to elongation in steel, the length of steel will be raised to some extent. Prior to arranging the bars in structural components, the steel bar should be cut, for this purpose, it is necessary to work out the perfect length of the bar …
Calculation Formula. The steel calculation formula is L x D2 /162 L = Length of bar D = diameter of bar. Steel Quantity of Column. Assuming the following data, column size is 450 x 600 x 3000 mm.

Apr 19, 2018· Requirement of binding wires for 1 ton (1000 kg) of steel reinforcement = 9 to 13 kg. Thus, binding wire required for tying 1000 kg of 8 mm bars is about to 12 kg and for 28 mm or 32 mm bars it will be approximately 7 kg. Greater the diameter of the bar, lesser the quantity of binding wire. Also read – BBS Of RCC Lintel Beam.

11-12-2014· Stirrups are provided between walls or support for a beam. No. of stirrups required for given beam = Length a = 450 - 2 x40 - 8 = 362mm Length b = 300 - 2 x 40 - 8 = 212mm Therefore, length of 1 stirrup S1 = 2 x (212 + 362 + 90) = 1328 mm Where 90mm is the minimum hook length as per IS 2502 - Table - II. Bar Bending Schedule for RCC Beam:
25-05-2015· Normally, steel bars have a 6m length. If length of a bar is not enough to keep the reinforcement, we have to lap two steel bars. 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 …
