Structural Damage Detection Using Digital Video Imaging and Wavelet Transformation

Non-contact measurement offers convenient and less expensive setup. Sometimes, they may also be the only resort because the structure is too small to be instrumented with contact sensors and/or the additional mass of the sensor is too large to use. In other cases, the structure is inaccessible due to obstruction for the case of tall/large structures such as bridges or towers. The digital imagin...

Damage Detection in Post-tensioned Slab Using 2D Wavelet Transforms

Earthquake force, loading more than structural capacity, cracking, material fatigue and the other unpredicted events were undeniable in the structure life cycle in order that environmental conditions of the structure would be changed and treats health. Damage of structures such as crack, corrosion of the post tension cables from inappropriate grouting of the post tension structures and etc. can...

Wavelet Transformation

Wavelet transformation is one of the most practical mathematical transformations in the field of image processing, especially image and signal processing. Depending on the nature of the multiresolution analysis, Wavelet transformation become more accessible and powerful tools. In this paper, we refer to the mathematical foundations of this transformation.   Introduction: The...

Structural Damage Detection Using Wavelet Support Vector Machine

Based on wavelet packet decomposition and conditions of the support vector kernel function, a nonlinear wavelet basis is introduced to construct the kernel function of support vector machine (SVM). A tighten wavelet support vector machine (WSVM), which has strong generalization ability is also obtained. In this study, a novel damage classification method based on wavelet support vector machine ...

A Damage Detection Algorithm Using the Morlet Wavelet Transform∗

In this paper, a damage detection algorithm based on the Morlet wavelet transform of the vibration signal is presented. In the rst part of the paper, an expression for the energies of wavelet coe cients (damage sensitive feature vectors) using the Morlet wavelet basis is derived for a multi-degree of freedom system. It is shown that the energies of the wavelet coe cients extracted at higher sca...
