Abstract

The article presents the results of theoretical research on the reliability of bending elements with a rectangular cross-section with single and double reinforcement. The influence of the coefficient of material properties connection is analyzed, along with formulas for calculating the load-bearing capacity of bending elements, considering variations in the parameters of concrete class and the percentage of reinforcement.

By utilizing statistical modeling methods, the strength of concrete and reinforcement was represented as randomly normally distributed variables. The dependency of the coefficient of material properties connection was determined for bending elements with a rectangular cross-section and single reinforcement, depending on the ratio , and for elements with double reinforcement, depending on the ratios of the percentages of upper compressed and lower tensile reinforcement, and ​ respectively.

The changes in this coefficient were analyzed in response to variations in the specified parameter ratios , ​, and ​. This analysis allows for the design of equally reliable reinforced concrete bending elements with a rectangular cross-section.
