Abstract
This article calculates the coefficients of variation and reliability indices of prestressed reinforced concrete structures by the bearing capacity of oblique sections for different combinations of a concrete class, reinforcement class, and reinforcement ratio. Based on the data obtained, a qualitative assessment of the influence of each factor, as mentioned earlier, on the reliability value of these structures is made, and recommendations for its regulation are developed. In most cases, there is a multidirectional change in the reliability and strength of oblique sections of the elements with an increase or decrease in a certain constructive factor. It is recommended to vary such factors as the concrete class and the reinforcement ratio to regulate the design reliability of elements by the bearing capacity of oblique sections designed per the current standards. As a result, the developed recommendations allow optimal design solutions, providing the target level of structural reliability without overspending the materials and funds.
