Post-installed adhesive anchor bolts are commonly used on all types projects, from standard buildings to bridges and nuclear power plants. They are exposed to varying and diverse environmental conditions which are significant successfully to make connections to concrete structures for many years. In order to maintain the safety and reliability of concrete structures such as buildings or bridges on higher level over a long period time, we developed a new non-destructive inspection system of adhesive anchor bolts based on hammering tests using AE (acoustic emission) sensor. It was confirmed that our developed inspection system based on hammering tests using AE sensor had a large potential to evaluate adhesive anchor bolts.
