Choose 1 answer: The conditional distribution of outcome for each game. David B. Distribution Bars. Number of Main Bars = Ly / spacing + 1 = (4000/150) + 1 = 27 nos. Step 5 -Calculation of Steel Weight. Longer span (l)/Shorter span (b) ≥ 2. Now we find the length of bar. Clear cover (top & bottom) = 50 mm. Lintel beam cover = 25mm. 1 m. So distribution bars help distribute loads among the main bars. Cutting length of bars. The distribution bars of the metric are 125 + 1 + 2 = 2000 divided by 2 + 2 = 125 + 2 = 18 bars. Here we have to calculate the number of main bar and distribution bar. The 2/0 lug terminal is designed for larger grounding needs, and. Numbers of Bars = Total length/ spacing of bar + 1 So, Numbers of main bars = 6000/100 +1 = 61 numbers And, Numbers of Distribution bars = 2000/125 +1 = 17 Numbers. STEP 7. Step 1. This video shows difference between Main bars and Distribution bars. Create a convenient central grounding point by connecting multiple ground wires. In the Flat-plate slabs, the main bars are provided in one direction at bottom of the distribution bar (in a shorter span). Chairs of minimum 12 mm diameter bars should be used. . And Distribution bar is the all-time install on the top of the main bar, this bar is also called a long bar. The area where the bars are concentrated, as a percentage of the width of the pile or column.
