Defect Signal Identification in Concrete-Filled Steel Tubular Columns Based on Wavelet Analysis
Based on the principle of acoustic energy distribution at a single flat interface under vertical ultrasonic incidence, this study derives the reflection and transmission coefficients for both healthy bonding interfaces and debonded interfaces in concrete-filled steel tubular (CFST) columns. The calc...

| description | Based on the principle of acoustic energy distribution at a single flat interface under vertical ultrasonic incidence, this study derives the reflection and transmission coefficients for both healthy bonding interfaces and debonded interfaces in concrete-filled steel tubular (CFST) columns. The calculation results indicate that when debonding defects occur in CFST, the signal amplitude received by the transducer on the same side increases significantly. By applying wavelet denoising and wavelet packet energy calculation methods to the experimental study of debonding damage identification at CFST interfaces, the area and extent of debonding defects can be accurately predicted. |
