  title={Transient Impact Response of Bridge I-Girders with and without Flaws},
  author={YiChing Lin and Kuo-Lung Lin},
  journal={Journal of Bridge Engineering},
This paper presents both numerical and experimental studies of the transient response of concrete I-girders with and without flaws subjected to transverse elastic point impact. These studies were aimed at evaluating the capability of using the impact-echo method for integrity testing of concrete I-girders. Numerical and experimental studies were performed first to gain an understanding of transient stress wave propagation in solid I-girder segments. Experimental studies were carried out on full… 
Frequency Spectrum Analysis of Impact-Echo Waveforms for T-Beams
Numerical and experimental studies were performed to assess the transient impact response of 11 T-beams with various dimensions and aspect ratios. Numerical modeling was performed using a three stage
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
Lamb wave basis for impact-echo method analysis
The impact-echo method has been developed over the past 20 years and is now widely used in the nondestructive evaluation of concrete. However, some practical issues remain unresolved, such as the
Nondestructive Damage Detection of Bridges: A Status Review
The recent advances in detecting and locating damage in bridges by different kinds of non-destructive testing and evaluation (NDT&E) methods are reviewed. From the application point of view,
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
Localization of grouting faults in post tensioned concrete structures
The investigation of post-tensioned tendon ducts is one of the very important and fascinating testing problems for concrete structures. Much progress was achieved in the past two decades including


Finite element studies of the impact-echo response of plates containing thin layers and voids
Quantitative nondestructive evaluation based on the use of transient stress waves generated by point impact is hindered by the fact that the governing partial differential equations admit closed-form
