ABSTRACT

Creep strain, a requirement of the concrete design process, is a complex phenomenon that has proven difficult to model. Although laboratory tests may be undertaken to determine the creep, these are generally expensive and not a practical option. Hence, empirical code-type prediction models are used to predict creep strain. This paper considers the accuracy of both the relatively new international fibModel Code 2010 and RILEMModel B4, when compared with the actual strains measured on a range of concretes under laboratory-controlled conditions. Both models investigated under-estimated the creep strain. In addition, the MC 2010 Model, which yielded an overall coefficient of variation (ωall) of 50.4%, was found to be more accurate than the RILEM B4 Model (with a ωall of 102.3%).
