abstract = {This paper presents a general procedure based on fracture mechanics models in order to analyze the level of cracking
and structural safety in reinforced concrete elements at early ages, depending on the stripping time. Our procedure
involves the development of a thermo-mechanical numerical model based on the finite element method that
accounts for the change in the mechanical properties of concrete with time. Moreover, fracture mechanisms are
analyzed by means of a material damage model, which is characterized via specific experimental results obtained for
standard specimens and notched beams under three-point bending testing. The loading conditions are both thermal
and mechanical, and are obtained from the hydration process for a given concrete dosage. The presented methodology
allows for the determination of the optimal stripping time, whereas it helps assessing the analysis of the cracking
and the stress states of the elements under consideration. A practical application, namely the analysis of a retaining
wall, is used to validate our methodology, showing its suitability in engineering practice.},
