Abstract

The article presents a methodology for monitoring the operational reliability of reinforced concrete structures of residential buildings based on the integrated use of modern non-destructive testing methods, mathematical modeling and forecasting. The study assessed the technical condition of the structures using visual inspection, instrumental measurements, mathematical modeling and the Monte Carlo method. As a result of visual inspection, 30% of cases of defects were identified, and instrumental measurements showed that the average concrete strength is 25 MPa, the reinforcement strength is 400 MPa. As a result of mathematical modeling, the loadbearing capacity of the structures was estimated at 7.5 MPa, which is lower than the concrete strength. Statistical analysis carried out by the Monte Carlo method revealed the probability of structure failure in 1500 cases out of 10000 simulations, which amounted to 15%. The proposed monitoring technique allows not only to identify defects, but also to assess the technical condition, as well as to predict the remaining service life, which is important for ensuring the safety and reliability of residential buildings. The integrated methodology for monitoring the operational reliability of reinforced concrete structures of residential buildings makes a significant contribution to the field of control and assessment of the reliability of structures that meet modern requirements.
