System for detection of defects in cables of bridge structures
An effective crack-identification approach for impact echo signals using MWT spectrograms and scaled FFT spectra
When performing an impact-echo (IE) test to detect internal cracks in concrete structures, the fast Fourier transform (FFT) of the measured surface responses is used to extract frequency peaks of
Debonding Detection in the Grouted Joints of Precast Concrete Shear Walls Using Impact-Echo Method
A grout layer between precast concrete components in an assembly structure is required to bear high axial loads and withstand significant shear forces during earthquakes. Since the grout layer
Evaluation of Unfilled Sheath in Concrete Structures Using Response Waveform in Time Domain
The impact elastic wave method (IEW) has been applied to evaluate the thickness and internal defects of the target structure based on the dominant frequency of the response wave that is formed by the

Evaluation of Steel Corrosion in Concrete Structures Using Impact-Echo Method
The impact-echo method is commonly used for detection of flaws in concrete elements based on the shift in the thickness frequency of a plate-like member. However, there is a need to develop this
Damage detection in steel fiber reinforced concrete using resonant method
Main aim of this work was to experimentally investigate steel fiber distribution in concrete, i.e. fiber segregation and nonuniform distribution, as well as possible internal cracks, with resonant
Grouting Defect Detection of Lapped Bar Connections Based on Impact-Echo Method
Grouted lap-splice connections are widely used for connecting precast concrete components. Grouting defects in the connections significantly influence the structural performance of the whole
An Embedded Tubular PZT Transducer Based Damage Imaging Method for Two-Dimensional Concrete Structures
TLDR
The experimental results conducted on a concrete slab with eight embedded tubular PZT transducers demonstrate that the proposed method can predict the defect accurately and efficiently even with few transducers and less experimental data.
