Creep and Shrinkage Effects
RAM Concept considers creep and shrinkage in any cross section by modifying the concrete stress-strain curves to be:
σ = f((ε - εcs )/ kc) |
= | ||
= | ||
= | ||
= | ||
= |
This modified concrete stress-strain curve is only used in the ECR calcs. It is never used for gross-section or cracked-section stress predictions.
