Statistical approach to determining the quantity of measurements when conducting instrumental inspection of building structures
Incoming article date: 28.05.2021Determination of the actual category of the technical condition of building structures is the main purpose of the survey. At the same time, the reliability of the survey results depends on the volume of instrumental measurement of the monitored parameters, which should be minimal, but sufficient to obtain data with a given level of security. This article presents a methodology for de-termining the scope of control based on a statistical approach with justification of the necessary and sufficient number of tests for each type of survey. The approbation of the described approach in the survey of precast concrete ele-ments is presented. The proposed methodology is based on a statistical approach adopted at the international level, which allows work to be carried out in other countries.
