Abstract

Impact echo method is an effective way to assess flaw in concrete. The commercially available impact echo analysis is interpreted manually, thus, to evaluate large area by the method is neither practical nor cost effective. In order to enhance the method in application to plate structure such as bridge decks, where duration of investigation plays substantial influence on traffic activity, data analysis and interpretation should not only be rapid and objective but also provide automatic mapping of deck quality at the end of investigation. This paper represents the development of algorithm for automatic impact echo data analysis in frequency domain and verification on the validity of the proposed method. The algorithm is developed to compensate the in field variation of thickness frequency (fT) of the investigated no defect portion of deck where a range of frequency at which fT would migrate is allowed. As a result, a software program can be developed based on this algorithm to eliminate the presence of skilled attendance during field investigation of slabs.
