- It presents the first concrete model that is able to capture the effects of the moisture content of the materials on its thermomechanical behaviour at high temperatures. The moisture-dependent components of both the free thermal strain and load-induced thermal strain are modelled through an original approach to capture the effects of moisture on the macroscopic material behaviour. The model is validated against the results of 130 existing transient tests. The work contributed to the prestigious 2018 Neville Prize for the best national PhD in concrete and generated EDF R&D projects worth £150k (contact: R&D Manager) to further develop the model.
