![]() ![]() The formula for Calculating Unit weight of Bar Step 4: Calculate the unit weight of Reinforcement Bar Length of Bar = Length of Concrete member (direction in which bar is placed) – (2 X Cover) + Development length Development Length Development Length Chart The formula, to calculate the length of those bars. Number of Bars = + 1 = 66 +1 = 67 Bars of 10 mm Día Step 3: Calculate the length of Reinforcement bars Suppose, 10 MM bars are distributed in the 10-meter-long slab at 150 mm c/c spacing, Considering the side cover of 50 mm. ![]() Number of Bars = (Concrete slab length in which bar is Distributed – 2 X Cover) / (c/c spacing between bars) + 1 To calculate a number of bars in big slab structure, you need to check the specific spacing between bars (center to center or c/c, its show in above fig) and the length of the concrete slab in which the bars are distributed. Now, Count the number of each different shapes of the bar and note down in bar bending schedule BBS Step By Step Preparation Step 2: Count the Number of bars ![]() The above image shows the number of bars like #5, #6, #9, etc, along with Día of the Bar (e.g. Now mark the diameter of Member in the table. Now, open a structural drawing and list down all the shapes of bar you see in the structural drawing. Step by Step Preparation of Bar Bending Schedule:įirst of all, download a Bar Bending Schedule excel sheet by Visiting Below Link to start with the calculation Step 1: Identification of Members (Steel Bars)Įach different type of Steel bar or Member is usually tagged with a number or bar mark in the structural drawing. It also makes easy for clients to approve bills for Payment.
