The compressive concrete stresses are described by Sargin [42] law, the average tensile stress located between two cracks is described by the relation of Grelat [15], the stress of the reinforcement is described by the perfect elastoplastic constitutive law recommended by the BAEL99 rules [43], and the behavior of prestressing reinforcements is represented by the law recommended by the BPEL99 rules [44] (Fig. 1).
