Abstract

This study explores the use of Acoustic Emission (AE) monitoring to evaluate the structural reliability of existing concrete structures during load testing. AE data were processed probabilistically to estimate crack locations and, combined with the strut-and-tie model, were used to assess shear resistance. Based on the processed AE data, a probabilistic framework was implemented to assess the structural reliability. The results demonstrate that incorporating AE significantly reduces the required load levels for indicating specific reliability index while maintaining safety during load testing. This research highlights the potential of AE as an efficient tool for reliability assessment of existing concrete structures.
