Annotation: Propositions for inprovement of modified strain theory variant developed in DonNACEA are presented. Analytical expressions, wich allow to subscribe the basic components for general case of volume stress state as elastic-plastic strains, wich don’t relate with destruction of concrete structure and pseudo-plastic strains due to regularities of concrete structure destruction, are made. As initial shear-displacement model of concrete structure destruction by type of three-dimentaional directed «zigzag crack» are adopted. Developed modified variant of concrete behavior model are formed up on the combination of solutions based on relations of solid mechanic and fracture mechanic. Verification of model are made by comparison of estimated values of A. V. Yashin, H. Kupfer, M. Tasuji и S. Schröder at conditions of unaxial stress states.
Keywords: concrete, volume stress state, strenth, strain, compressibility, dilatation, behavior models.
