Application of guided waves in the evaluation of steel-concrete adhesive connection
The aim of the paper is the application of guided waves in the evaluation of a condition state of adhesive connection between steel and concrete. The study concerns a push-out specimen consisting of two steel plates glued to opposite faces of a concrete cube with the use of structural adhesive. Wave propagation in the specimen without external load is investigated both experimentally and numerically. The second stage of the investigation is the wave propagation analysis at various states of mechanical degradation during the push-out test. The obtained results are evaluated in terms of a possible application of guided waves for inspection of adhesive bonding in steel-concrete systems.
