Empirical Formula for Secant Modulus Proposed by Hognestad in ACI Code Solution

STEP 0: Pre-Calculation Summary

Formula Used

Secant Modulus = 1800000+(460*Cylinder Strength)
E_c = 1800000+(460*f_c')
This formula uses 2 Variables

Variables Used

Secant Modulus - (Measured in Pascal) - Secant Modulus is one of several methods used to calculate modulus of elasticity, which is a measurement of a material's elasticity.
Cylinder Strength - (Measured in Pascal) - Cylinder Strength is the characteristic strength of concrete which is tested on a cylinder having 30cm height and 15cm diameter.

STEP 1: Convert Input(s) to Base Unit

Cylinder Strength: 0.65 Megapascal --> 650000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

E_c = 1800000+(460*f_c') --> 1800000+(460*650000)

Evaluating ... ...

What is Tangent Modulus?

Tangent Modulus is defined as the slope of a line tangent to the stress-strain curve at a point of interest. Tangent modulus can have different values depending on the point at which it is determined. For example, tangent modulus is equal to the Young's Modulus when the point of tangency falls within the linear range of the stress-strain curve. Outside the linear elastic region, at point A shown for example, tangent modulus is always less than the Young's modulus.

What is Secant Modulus?

Secant Modulus is the slope of a line drawn from the origin of the stress-strain diagram and intersecting the curve at the point of interest. Therefore, the secant modulus can take different values depending on the location of intersect.
