[en] This paper presents a new formulation of the generic Eurocode 2 concrete
model that contains an explicit term for consideration of the transient creep. The
simplicity and generic characteristics of the Eurocode model are preserved and the
new explicit formulation is calibrated to give the same results as the implicit
formulation that is proposed in the Eurocode when the material is heated under
constant load. However, the improvements allow taking into account with more
accuracy the phenomenon of transient creep in concrete under more complex
situations such as, for example, the cooling phase of a fire. The differences between
the two formulations are highlighted for a simple structure. A comparison is given
between experimental and calculated results on a centrally loaded concrete column
submitted to heating-cooling sequence.
