The questions of rationing the reliability of building structures excited many researchers. They have complex solutions that are related to the economic and non-economic (social) consequences of failures. Tf the former can be taken into account in the calculation, the second accounts are not always amenable. The task of normalizing the reliability of building structures by deformations is related to the consideration of both failure consequences types. Knowing the value of normative reliability by deformations is just as important as knowing the value of normative reliability in terms of carrying capacity, because it solves a number of social and technical problems. The difficulty of finding the value of normative reliability by deformation for the majority of designs is that non-economic (social) consequences are likely to prevail over economic ones. The article proposes methods for determining the standard reliability for deformations of reinforced concrete bent structures. The method of determination is considered taking into account the economic consequences of the refusal, but a more detailed procedure is presented that presumes taking into account the noneconomic (social) consequences of the refusal. The calculation is based on the sensitivity of a person to vibrations that occur when deformation of structures. The proposed methodology for calculating the normative reliability, taking into account non-economic (social) consequences, takes into account only the physiological requirements imposed on the deformations of the structures.
