New features in SAFIR: Transient Creep in Eurocode Concrete Model

A new formulation of the Eurocode 2 concrete model at elevated temperature has been implemented in which the transient creep strain is treated by an explicit term in the strain decomposition. This new model gives the same answer as the Eurocode model when the load and the temperature increase, but the new model is better than the Eurocode model at capturing the concrete behavior when the load or the temperature decrease owing to the explicit transient creep term. This new concrete model, called Explicit Transient Creep Eurocode model (ETC), has been implemented in the software SAFIR.
