Total Number of Main Bars Solution

Follow our step by step solution on how to calculate Total Number of Main Bars?

FIRST Step Consider the formula

No main bars = (\frac{L clear(longer side)}{S bar}) + 1

Next Step Substitute values of Variables

∴

No main bars = (\frac{6001mm}{150mm}) + 1

Next Step Convert Units

∴

No main bars = (\frac{6.001m}{0.15m}) + 1

Next Step Prepare to Evaluate

∴

No main bars = (\frac{6.001}{0.15}) + 1

Next Step Evaluate

∴

No main bars = 41.0066666666667

LAST Step Rounding Answer

∴

No main bars = 41.0067

Go Total Number of Distribution Bars

No distribution bar = (\frac{L clear(short side)}{S bar}) + 1

Go Cutting Length of Main Bar

L main bar = L clear(short side) + (2 \cdot W beam) - (2 \cdot C slab) + (0.42 \cdot d eff) - (2 \cdot d)

Go Cutting Length of Distribution Bar

L dist bars = L clear(longer side) - (2 \cdot C slab)

How to Evaluate Total Number of Main Bars?

Total Number of Main Bars evaluator uses Number of Main Bars = (Clear Span of Longer Side/Spacing between Bars)+1 to evaluate the Number of Main Bars, The Total Number of Main Bars formula is defined as calculating the number of main bars needed for the RCC slab of a given cross-sectional area. Number of Main Bars is denoted by No_{main bars} symbol.
