摘要
PURPOSE: A non-destructive inspection method for a concrete structure is provided to improve accuracy of inspection on crack of the concrete structure by removing an error resulting from attachment of a sensor. CONSTITUTION: A non-destructive inspection method for a concrete structure comprises steps of: generating stress wave in the concrete structure using a transducer(S10), measuring the stress wave generated by the concrete structure(S20), interpreting the measured stress wave in a frequency domain(S30), removing an error according to the attachment of the transducer to estimate the transfer speed and energy of the stress wave(S40), and evaluating the concrete structure based on the transfer speed and energy of the stress wave(S50).
