Monitoring of active destructive processes as a diagnostic tool for the structure technical state evaluation

Abstract

In this paper, a global monitoring system based on the measurement of acoustic emission (AE) due to active deterioration processes is presented. This allows us to examine the entire volume of an element and to locate and identify the type and the dynamics of the deterioration processes under service conditions. The resulting data are used to determine and locate the damage processes that are dangerous in construction made of pre-stress concrete, steel and fiber glass and to assess the general condition of the structure.
