Steel Ratio Solution

Follow our step by step solution on how to calculate Steel Ratio?

FIRST Step Consider the formula

ρ steel ratio = \frac{A}{b \cdot d'}

Next Step Substitute values of Variables

∴

ρ steel ratio = \frac{10m²}{26.5mm \cdot 7547.15mm}

Next Step Convert Units

∴

ρ steel ratio = \frac{10m²}{0.0265m \cdot 7.5472m}

Next Step Prepare to Evaluate

∴

ρ steel ratio = \frac{10}{0.0265 \cdot 7.5472}

Next Step Evaluate

∴

ρ steel ratio = 50.0001312503445

LAST Step Rounding Answer

∴

ρ steel ratio = 50.0001

How to Evaluate Steel Ratio?

Steel Ratio evaluator uses Steel Ratio = (Area of Tension Reinforcement)/(Beam Width*Distance from Compression to Centroid Reinforcment) to evaluate the Steel Ratio, The Steel Ratio is defined as the ratio of area of tension reinforcement to that of the product of beam width and distance from extreme compression to centroid of reinforcement. Steel Ratio is denoted by ρ_{steel ratio} symbol.

How to evaluate Steel Ratio using this online evaluator? To use this online evaluator for Steel Ratio, enter Area of Tension Reinforcement (A), Beam Width (b) & Distance from Compression to Centroid Reinforcment (d') and hit the calculate button.

FAQs on Steel Ratio

What is the formula to find Steel Ratio?

The formula of Steel Ratio is expressed as Steel Ratio = (Area of Tension Reinforcement)/(Beam Width*Distance from Compression to Centroid Reinforcment). Here is an example- 50.00013 = (10)/(0.0265*7.54715).

How to calculate Steel Ratio?

With Area of Tension Reinforcement (A), Beam Width (b) & Distance from Compression to Centroid Reinforcment (d') we can find Steel Ratio using the formula - Steel Ratio = (Area of Tension Reinforcement)/(Beam Width*Distance from Compression to Centroid Reinforcment).
