“…NDT is one part of structural health monitoring where generally in SHM basic fundamental dynamic characteristics of structure including fundamental modal parameters were used to understand development of damage on monitored structure [1,2,3,4]. This technique provide user the global response of the structure whereas AE technique generally used for localize damage assessment [5]. Each of the NDT method has its own benefits and disadvantages depending on the materials and conditions of the tested specimens or structures.…”

The selection of reliable technique for damage assessment is important in civil engineering structure. The present study proposed Acoustic emission (AE) technique by using the fundamental AE parameter to evaluate damage accumulated on Ultra High-Performance Concrete (UHPC) specimens. The UHPC beam with dimension of 515 mm x 98 mm x 98 mm was tested under three-point bending test with stepwise flexural load. In order to detect and to collect the AE data, Micro-SAMOS (μ-SAMOS) digital AE system and R6I sensors type were used while data analyses were carried out using AEwin software. The damage level that take place during increasing static loading on tested concrete beams and the mechanism was successfully evaluated using the AE technique.
