Modulus of Rupture of Concrete Solution

STEP 0: Pre-Calculation Summary

Formula Used

Modulus of Rupture of Concrete = 7.5*((Characteristic Compressive Strength)^(1/2))
f_r = 7.5*((fck)^(1/2))
This formula uses 2 Variables

Variables Used

Modulus of Rupture of Concrete - (Measured in Pascal) - Modulus of Rupture of Concrete is a measure of the tensile strength of concrete beams or slabs.
Characteristic Compressive Strength - (Measured in Pascal) - The characteristic compressive strength is defined as the strength of the concrete below which not more than 5% of the test results are expected to fall.

STEP 1: Convert Input(s) to Base Unit

Characteristic Compressive Strength: 20 Megapascal --> 20000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f_r = 7.5*((fck)^(1/2)) --> 7.5*((20000000)^(1/2))

Evaluating ... ...

f_r = 33541.0196624968

STEP 3: Convert Result to Output's Unit

33541.0196624968 Pascal -->0.0335410196624968 Megapascal (Check conversion here)
