On the modeling of the dehydration induced transient creep during a heating–cooling cycle of concrete
Abstract A thermo-hydro-mechanical coupled model is presented here in order to simulate the transient creep strain of the load induced thermal strain of concrete during a heating–cooling cycle with a concomitant applied load. In this paper, the transient creep strain is split into a drying creep component and a dehydration creep strain. Further, a dehydration variable is introduced to describe chemical transformations due to the temperature increase. It also allows to govern the occurrence of the transient creep strain. Moreover, in this approach, we consider that the dehydration creep occurs with the same kinetics as the dehydration process. This model has been implemented in the finite element code CAST3M and numerical simulations are performed to assess the capability of the model to predict transient load induced thermal behavior of concrete in the case of a heating cooling cycle.
