The Algorithm and program for calculating for the strength, deformation and fracture toughness of reinforced concrete structures. It has been improved under various regimes of slightly-repeated loads on the basis of the development of scientific ideas about the effect of the own field of stresses of concrete with the EMBALIT and SP, as well as the establishment of low-cycle fatigue strength of such concretes and limits fatigue strength from the main factors. The main regularities of development of own deformations and stresses of concrete during hardening under conditions of restriction of expansion deformations and without restriction are revealed.
