Application of the Acoustic Emission Method in the Assessment of the Technical Condition of Steel Structures

In accordance with applicable international regulations, construction products and elements should have appropriate physical and strength features to meet the required limit states of load-bearing capacity and serviceability in the construction objects designed by them throughout their entire lifetime. The non-destructive methods should be used to assess physical and strength features at various stages of implementation and operation. The complexity of security problems, reliability and durability in the conditions of use of modern building structures therefore requires the development and improvement of specialized research methods. Diagnostics and assessment of building objects requires the use of optimal "in situ" research methods that allow for the assessment of the boundary states of buildings with sufficient accuracy over the entire lifetime. The article presents application the acoustic emission signal (AE) in the diagnosis of technical facilities. The equipment used for signal acquisition is described. An example area of application of the AE method in technology is presented - monitoring of the technical condition of steel structures. Recording and analyzing the AE signal proved to be an effective tool in the diagnosis of this type of construction.
