To the Definition of Regulatory Reliability on the Deformation of Reinforced Concrete Bending Structures Based on the Aesthetic and Psychological Requirements Abstract. Calculation of any building structure is made to ensure strength, rigidity, stability and efficiency. Currently, all calculations are performed by the method of limit states, but the rules allow the use of the probabilistic calculation method in the presence of the necessary initial data. The purposes of calculations by this method are the same as for the calculation by the method of limit states. When using probabilistic methods, great attention is paid to the calculation of the building structures strength. This is true because this calculation is a priority compared to other calculations. But other calculations, such as the calculation of deformations, are also necessary. One of the application problems of probabilistic methods calculation is the normalization of the failure probability. If in the normalization of the failure probability in the calculation of the bearing capacity there are certain reasonable solutions, then on the normalization of the failure probability to work on the deformations of such solutions, as a rule, no. The issue of rationing the failure probability is always relevant. Without knowledge of the normalizing indicator value it is impossible to correctly calculate any building structure by probabilistic methods. This article proposes a method for determining the standard probability of failure-free work on deformations, based only on the aesthetic and psychological requirements for the ultimate deflection of structures. The proposed method is applicable to the bent reinforced concrete structures and is based on the probabilistic-optimization model.
