There are many calculation methods for layered structures in scientific literature, but in most cases these calculation methods are complicated and inapplicable for layered structures made of reinforced concrete. Moreover, most of the calculation methods do not estimate the possibility of appearance of the cracks in the internal layers before the cracks in external layer in which the tensile stresses are higher. The internal layers could be made of lightweight concrete type materials (e.g. foamed concrete) which shrinkage deformations are several times higher if compared to the external layers. Therefore, the cracks in the internal layer may appear even before actual loading of the structure. The flexural layered members may have very complex state of stress and strain. Such state of stress and strain should be estimated when designing the effective and reliable building structures. The proposed method for the calculation of carrying capacity and cracking moment of the external layer of flexural layered reinforced concrete structures estimates the cracking of the internal layer, concrete shrinkage deformations and the physical and mechanical properties of used materials.
