“…That is, in order to obtain a more informative result, it becomes necessary to combine random variables (in terms of probability theory) and fuzzy variables (in terms of the theory of possibilities) when performing calculations on the reliability of building structures. This article presents the possibility of implementing such a combination of random variables and fuzzy variables on the basis of a modernized reliability calculation method [11,12] on the example of the proposed private method for calculating the reliability of brickwork of a building by the strength criterion.…”

In order to change the appearance of buildings or structures during major repairs and reconstruction, hinged ventilated facade systems are often used. To make a decision on the possibility of using a hinged ventilated facade, it is necessary to assess the technical condition of the bearing and enclosing structures of the building or structure in question, including determining their reliability. The article proposes a particular method for calculating the reliability of brickwork by the strength criterion, based on the combined method, for the case when the statistical information obtained as a result of the survey is complete in part of the controlled parameters, and in the other part of the parameters – not complete, since the use of a probabilistic method for calculating reliability will lead to the loss of some useful statistical information, since all parameters are represented as fuzzy variables, and the use of probabilistic statistical methods may lead to incorrect calculation results, since the assumption of the distribution law for the controlled parameters may be erroneous.

Issues of safe operation of buildings and structures in the Russian Federation are regulated by various legal and regulatory and technical documents, including Federal Law No. 384 "Technical Regulations on the safety of buildings and structures", to which is attached a list of documents with the status of mandatory, including GOST 27751-2014 "Reliability of building structures and foundations. The main provisions". In this normative document, it is proposed to calculate the reliability of building structures using probabilistic and statistical methods that can be used only in cases where there is complete, homogeneous and statistically independent information about the controlled parameters, while there are no instructions on how to calculate the reliability of building structures if it is impossible to obtain statistical information as a result of the survey and monitoring of building structures. information on controlled parameters, allowing to reliably identify the distribution law and its parameters. The article proposes a particular method for calculating the reliability of a centrally compressed column made of an I-beam with a cross-corrugated wall according to the stability criterion, in which part of the controlled parameters are considered as random variables with complete statistical information, and the other part of the parameters having incomplete statistical information is considered as fuzzy variables. The combination of random variables and fuzzy variables in calculating the reliability of the column made it possible to more fully take into account statistical information about the controlled parameters.
