Abstract
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.
