Empirical Formula for Secant Modulus using ACI Code Provisions

Go Secant Modulus = Unit Weight of Material^1.5*33*sqrt(Cylinder Strength)

Total Strain given Creep Coefficient

Go Total Strain = Instantaneous Strain*Creep Coefficient

Creep Coefficient in European Code

Go Creep Coefficient = Total Strain/Instantaneous Strain

Instantaneous Strain given Cc

Go Instantaneous Strain = Total Strain/Creep Coefficient

Total Strain

Go Total Strain = Instantaneous Strain+Creep Strain

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.
