Big Mistake In BBS of Slab || आप मत करना यह गलती ||

Slabs are mainly two types one way slab and two way slab. One way slab is a slab that is supported on two opposite sides and carries the load in one direction. The ratio of longer span to shorter span is equal to or greater than 2. i.e l/b equal and less than 2. In two way slab, the slab is supported by four sides and loads are carried along with both directions. The ratio of longer span to shorter span is less than 2. i/e l/b less than 2. Go through the complete article to get an idea of how to prepare bar bending schedule of slab. Ly/Lx = Longer span/shorter span = 5000/2000 = 2.5 greater than 2 It is a one way slab. Given, Length of slab = 5000 mm Width of slab = 2000 mm Main bar = 12 mm @ 150 mm c/c Distribution ber = 8 mm @ 150 mm c/c Clear cover (Top and bottom) = 25 mm Thickness of slab = 150 mm Development length = 40d Where d is dia of bar. Bar Bending Schedule Of Slab (One Way) Step 1: Calculate no. of bars First, calculate the number of bars required for main bars and distribution bars. No. of bars = Length of slab/spacing + 1 No. of main bars = Lx/Spacing + 1 = 5000/150 = 34 No. of distribution bars = Ly/Spacing + 1 = 2000/150 +1 = 14 Step 2: Calculate cutting length of main bars and distribution bars. Cutting length of main bar = Clear span of slab + (2 x development length) + Inclined length – (Bend length) Clear span of slab = 2000 mm Big Mistake In BBS of Slab || आप मत करना यह गलती || Positive Builder Avinash Sharma
