The article provides valuable information on methods for assessing the reliability of stone structures. The authors draw attention to the issues of diagnostics and calculation of the reliability of existing masonry structures, and also offer methods for determining the compressive strength of masonry using the theory of reliability. The destructive and non-destructive tests underlying the determination of strength masonry are also described.
The authors emphasize the importance of structural safety and reliability, which depend on many factors, including the type and magnitude of loads and the bearing capacity of structural elements. A sufficient state of safety is ensured by compliance with the relevant standards and regulations.
The article draws attention to the importance of carrying out tests and calculations in the reconstruction and repair of buildings in order to guarantee their safe operation. The authors note that the safety and reliability of the design also depends on compliance with the rules and regulations that take into account the social, economic and environmental consequences of failure.
The emphasis on the probabilistic approach to assessing the reliability of a design is an important aspect of the article. Taking into account the probability of failure allows us to develop a rational approach to the repair and reconstruction of buildings, ensuring their normal operation. The authors also draw attention to the importance of determining the probability of failure (Pf) as a fundamental parameter for its assessment.
