The paper offers developed expressions for describing concrete deformation diagrams at uniaxial short-time tension/compression using the theory of damage accumulation related to the perspective direction for description of damage processes taking place in building materials and constructions. It is reached by introducing the deformation criterion of damageability to the dependences «σ - ε». The reliability of the results received by the diagram construction method has been checked on the example of some bent concrete and reinforced concrete elements. There has been carried out a comparison analysis of the Mcrc crack formation moments and the Mult damage moments calculated by the technique according to the SNiP (Construction Norms and Regulations) 2.30.01-84* accepted as the standard and according to the proposed approach.
