This article analyzes the assessment of the signs leading to the possible destruction of the studied building structure. To determine the degree of influence of signs (or groups) on the level of structural failure in their direct diagnosis, it is possible to use a mathematical basis, in particular, the Bayesian approach. The essence of the implementation is to compare the probability of failure for each structure under study. The result of the work is to identify and describe not only the features of the relationship between each feature affecting the destruction of the structure and the calculated probability of destruction, but also their degree of influence on increasing or decreasing the probability of an accident. According to the estimates of the mathematical definition of the signs affecting the destruction of the building structure, it is possible to more objectively assess the effectiveness of the method used to check the condition of the building structure.
