The reliability of building structures is one of the key indicators of mechanical safety. Modern problems of assessing the reliability index of building structures related to the analysis of statistical data and the construction of mathematical models of limit states are considered. The use of p-boxes as promising and effective models of random variables making it possible to describe more validly probability distribution functions is demonstrated. The numerical example of the reliability index evaluation reflects the fact that even samples based on a large volume of experimental data require the use of the provisions of interval analysis, fuzzy analysis and other modern theories of data analysis. A numerical example shows the problem of invariance of mathematical models of limit states for probabilistic reliability analysis, as a result of which different forms of one mathematical model lead to different estimates of the reliability index. The development of numerical methods for calculating building structures and the increase in computing power does not make it possible to increase the reliability of probabilistic assessment of the reliability of building structures based on classical probabilistic and statistical methods. There is a need to develop reliability analysis methods based on modern methods and computational algorithms. Perspective directions for the development of methods for analyzing the reliability of building structures are noted.
