Evaluation of Reinforced Concrete Structures with Magnetic Method and ACO (Amplitude-Correlation-Offset) Decomposition

The magnetic method is one of the very few nondestructive testing (NDT) techniques that provide possibility to conduct area tests reinforced concrete (RC) structures in a fast, cheap, and straightforward way. This paper aims present new approach simultaneous identification rebars’ diameter, alloy class, thickness cover tested with this method. Since rebars from different manufacturers may have electromagnetic properties (standardization only for mechanical properties), preparing an effective universal database impossible. In work, ACO decomposition proposed, attributes extraction designed identify object parameters, even if it impossible collect suitable training (by pattern recognition analysis deviation). Conducted prove enables accurate reflection waveform shape limitation number three or fewer (avoiding curse dimensionality). These properties, combined ability analyze spatial components induction (which sensors provide), make complex task parameters more separation between results received classes larger. article presents measurement whole process.
