Abstract
Durability, safety, and usability are the three foundations of structural reliability, vital in the economic and social context. As the locating and tracking of potential damage and evaluating its impact on the condition of the structure are part of service life assessment, relevant methods should be developed that would detect the onset of the deterioration process and enable the monitoring of its progress within the entire volume of the structure, not only in the areas selected in a subjective way. The acoustic emission (AE) method relying on the analysis of active destructive processes can be the best choice. This article reports the results of the application of the AE method for identifying active destructive processes and tracking their development during the routine operation of various types of structures.

Structural condition diagnostics and monitoring are two important issues in the economic and social context
Aging infrastructure, deteriorating environmental conditions, and increasing operational loads are the primary stimuli for fast-progressing research on a new interdisciplinary field of technical knowledge called “Structural Health Monitoring (SHM)”, closely connected to the safe service life of structures [1,2]
The examples of acoustic emission evaluation of various types of engineering structures and the proposed global monitoring based on the measurement of acoustic emission structures signals
Summary
Structural condition diagnostics and monitoring are two important issues in the economic and social context. Aging infrastructure, deteriorating environmental conditions, and increasing operational loads are the primary stimuli for fast-progressing research on a new interdisciplinary field of technical knowledge called “Structural Health Monitoring (SHM)”, closely connected to the safe service life of structures [1,2]. The author’s attention will be focused on assessing the structural integrity of existing facilities and its impact on their durability. Durability, safety, and usability are the three foundations of structural reliability. The durability factor is, unlike in the past, important and has to include the evaluation of environmental impacts (moisture, frost, CO2 , de-icing agents, etc.) on the present and future health of the structure
