A co-rotational total Lagrangian formulation for the non-linear analysis of reinforced concrete beams under severe thermo mechanical loads is presented. The advantage of the proposed procedure is its ability to consider realistic constitutive relations for concrete and steel including wide range phenomena such as transitional thermal creep, plasticity, cracking, and degradation of material properties within the framework of large displacements and small strains theory. Results have indicated that the model predictions compare well with experimental data obtained on beams tested in severe fire environments.
