Methodology for Assessing the Technical Condition of Buildings and Structures Using the Reliability Criterion

Abstract

As a result of the design and construction of buildings and structures, the level of reliability of the construction structure or construction object as a whole is formed. The reliability specified in the project does not remain constant, but changes over time as a result of the imperfection of the design model of the building, inaccuracies of installation, as well as during the accumulation of defects and damage to the building during its use. Currently, the scope of work related to the assessment of the technical condition of buildings is constantly increasing. This is due not only to the increasing number of operated structures, but also an increase in safety requirements and an increase in the qualitative characteristics of buildings. The article proposes to maintain a unified approach to the inspection of the engineering and technical condition that uses the reliability criterion for the basic structural elements of buildings and structures. In modern conditions, it is important to determine the necessary level of reliability acceptable to economic considerations and meets modern safety requirements. It is important to calculate the numerical threshold values of the categories of the technical condition of building structures to eliminate the subjective approach to the assessment of their technical condition.
