Abstract: The results of a study of the bearing capacity and deformability of non-centrally compressed reinforced concrete composite elements of low flexibility, made by concreting prefabricated elements to the design cross-section dimensions, are presented. The joint work in the composite section of concretes with various strength and deformation characteristics under short-term and long-term loading, the influence of loading history on the deformability of long-term loaded non-centrally compressed reinforced concrete elements, the mechanism of redistribution of internal forces between the components of the section during loading and over time, the nature of destruction of prototypes is established. It has been established that the joint work of concretes with various deformative characteristics significantly increases the ultimate compressibility of these concretes. With prolonged action of an off-center applied load on elements of low flexibility, the possibility of reaching the limiting state of the second group was revealed.
