Concrete Shear Strength at Critical Sections Solution

Follow our step by step solution on how to calculate Concrete Shear Strength at Critical Sections?

FIRST Step Consider the formula

V = (2 \cdot {(f c)}^{\frac{1}{2}}) \cdot d' \cdot b o

Next Step Substitute values of Variables

∴

V = (2 \cdot {(15MPa)}^{\frac{1}{2}}) \cdot 10mm \cdot 0.54m

Next Step Convert Units

∴

V = (2 \cdot {(1.5E+7Pa)}^{\frac{1}{2}}) \cdot 0.01m \cdot 0.54m

Next Step Prepare to Evaluate

∴

V = (2 \cdot {(1.5E+7)}^{\frac{1}{2}}) \cdot 0.01 \cdot 0.54

Next Step Evaluate

∴

V = 41.8282201390401Pa

LAST Step Rounding Answer

∴

V = 41.8282Pa
