Total Number of Distribution Bars Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Distribution Bars = (Clear Span of Shorter Side/Spacing between Bars)+1
No_{distribution bar} = (L_{clear(short side)}/S_bar)+1
This formula uses 3 Variables

Variables Used

Number of Distribution Bars - Number of Distribution Bars is the number of reinforcement bars that are placed above the main bar in a one-way slab, to distribute load to the main bar.
Clear Span of Shorter Side - (Measured in Meter) - Clear Span of Shorter Side is the clear distance between two support (column, wall etc.).
Spacing between Bars - (Measured in Meter) - Spacing between Bars is the distance between two consecutive bars in the slab.

STEP 1: Convert Input(s) to Base Unit

Clear Span of Shorter Side: 2500 Millimeter --> 2.5 Meter (Check conversion here)
Spacing between Bars: 150 Millimeter --> 0.15 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

No_{distribution bar} = (L_{clear(short side)}/S_bar)+1 --> (2.5/0.15)+1

Evaluating ... ...

No_{distribution bar} = 17.6666666666667

STEP 3: Convert Result to Output's Unit

17.6666666666667 --> No Conversion Required

FINAL ANSWER

17.6666666666667 ≈ 17.66667 <-- Number of Distribution Bars

Total Number of Distribution Bars Formula

Number of Distribution Bars = (Clear Span of Shorter Side/Spacing between Bars)+1
No_{distribution bar} = (L_{clear(short side)}/S_bar)+1

What are Distribution Bars?

The reinforcement bars that are placed above the main bar in a one-way slab, to distribute the superimposed load to the main bar are called distribution bars.
The distribution bar helps to firmly hold the main bars in their assigned position. They also act against shrinkage stresses due to temperature variations.

What are the functions of Distribution Bars?

The functions of distribution bars are as under
1. Distribution bars are provided to resist the shear stress and cracks developed in the longer span.
2. Distribution bars are provided perpendicularly to the top of the main bar.
3. Lesser dimension bars are used.
4. Distribution bars are provided in the longer span direction.

How to Calculate Total Number of Distribution Bars?

Total Number of Distribution Bars calculator uses Number of Distribution Bars = (Clear Span of Shorter Side/Spacing between Bars)+1 to calculate the Number of Distribution Bars, The Total Number of Distribution Bars formula is defined as calculating the number of distribution bars to be used for the RCC slab of a given dimension. Number of Distribution Bars is denoted by No_{distribution bar} symbol.

How to calculate Total Number of Distribution Bars using this online calculator?
