What is difference between creep and shrinkage?
In shrinkage, the loss is due to difference in the relative humidity of concrete and the environment, in creep it is due to sustained applied stress. The factors that effect creep also effects shrinkage. They both increase with: higher cement content, higher water content, lower aggregate content, low relative humidity, high temperature, small thickness of the member, etc.
How to Calculate Creep Coefficient given Creep Strain?
Creep Coefficient given Creep Strain calculator uses Creep Coefficient = Ultimate creep strain/Elastic strain to calculate the Creep Coefficient, Creep Coefficient given Creep Strain refers to ratio of concrete creep amplitude value to instantaneous strain. Creep Coefficient is denoted by Φ symbol.
How to calculate Creep Coefficient given Creep Strain using this online calculator? To use this online calculator for Creep Coefficient given Creep Strain, enter Ultimate creep strain (ε_{cr,ult}) & Elastic strain (ε_{el}) and hit the calculate button. Here is how the Creep Coefficient given Creep Strain calculation can be explained with given input values -> 10 = 0.5/0.05.
