RILEM draft recommendation: TC-242-MDC multi-decade creep and shrinkage of concrete: material model and structural analysis*

Model B4 for creep, drying shrinkage and autogenous shrinkage of normal and high-strength concretes with multi-decade applicability

RILEM Technical Committee


In response to the continuously advancing concrete technology, a new prediction model for creep and shrinkage is presented. This model, named B4, builds on the theoretically justified model B3, which is a RILEM recommendation from 1996. Improvements to the model allow for enhanced multi-decade prediction, distinguish between the drying and autogenous shrinkage, and introduce new equations and parameters to capture the effects of various admixtures and aggregate types. The development and justification of the model is described in three companion articles which follow.
