New FA-PI Method Enhances Defect Detection in Concrete Structures

Researchers have developed a new method called Frequency-Amplitude Persistence Image (FA-PI) to improve the detection of defects in concrete structures using impact-echo testing. This technique constructs a two-dimensional image from the Fourier amplitude spectrum, representing frequency-bin location and amplitude. FA-PI was evaluated on experimental and public datasets, demonstrating superior performance over traditional raw and smoothed Fourier spectra, particularly in noisy conditions. The findings suggest that this 2D spectral representation enhances defect classification accuracy. AI

IMPACT This research could lead to more reliable and accurate non-destructive testing methods in civil engineering and infrastructure maintenance.
