Effective Concrete Area given Force in Slab Solution

Follow our step by step solution on how to calculate Effective Concrete Area given Force in Slab?

FIRST Step Consider the formula

A concrete = \frac{P on slab}{0.85 \cdot f c}

Next Step Substitute values of Variables

∴

A concrete = \frac{245kN}{0.85 \cdot 15MPa}

Next Step Convert Units

∴

A concrete = \frac{245000N}{0.85 \cdot 1.5E+7Pa}

Next Step Prepare to Evaluate

∴

A concrete = \frac{245000}{0.85 \cdot 1.5E+7}

Next Step Evaluate

∴

A concrete = 0.0192156862745098m²

Next Step Convert to Output's Unit

∴

A concrete = 19215.6862745098mm²

LAST Step Rounding Answer

∴

A concrete = 19215.6863mm²
