Strength, stiffness, crack resistance requirements must be specified for any structure. These requirements are provided by the appropriate calculations. Compliance with all requirements ensures the design reliability. But due to the fact that structural analysis is performed by the limit state method, the numerical value of the reliability cannot be determined. This can be done only by applying probabilistic methods of calculation. One of the major obstacles to the use of probabilistic methods
more » ... babilistic methods is the lack of standardized values of the structural reliability (normative reliability).Although probabilistic methods of calculation were developed in late in the 20th century, the assignment of normative reliability values encountered serious obstacles. The most serious obstacle was the consideration of the failure consequences as some consequences were quantifiable. On the other hand, much work concerned the assignment of normative structural reliability based on their bearing capacity. Only few works related to the reliability normalization using deformation and crack resistance.This paper deals with the regulatory definition of reliability using the deformation of reinforced-concrete bendings based on physiological requirements. A method for determining the normative reliability based on human sensitivity to fluctuations is proposed. The normative reliability of precast slabs is determined using the proposed method.
