PREDICTION OF THE SERVICE LIFE OF MODERN STRUCTURES BASED ON ASSESSMENT OF CRACK RESISTANCE

This article presents a new method for assessing the crack resistance of modern building structures using the example of predicting the service life of a critical element in a residential building. One of the key aspects of evaluating the durability of damaged structures is analyzing the dynamics of crack width changes. Measuring the crack width makes it possible to assess the degree of degradation of load-bearing elements and predict the moment of failure. The new method is based on considering a cracked, loaded structural element as a dynamic system operating in a blow-up mode. This assumption provides researchers with a tool to forecast the remaining service life of the construction element up to the point of uncontrolled defect development. The example provided in the article, involving the prediction of the service life of a wall partition, clearly demonstrates the effectiveness of this approach to evaluating the durability of residential buildings.
