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