The more application of visualization techniques in medicine, geology and other fields is employed, but less use in structural damage detection area. This paper presents visualization of damaged rail, in which the damage has been identified via wavelet transform. First, a simulation of intact and single damages rail was carried out. Then, the displacement modes of intact and damaged rail are extracted...
The more application of visualization techniques in medicine, geology and other fields is employed, but less use in structural damage detection area. The damage detection results in arch structure are visualized in this paper. First, the displacement modes of intact and damaged arch are simulated and the displacement mode changes are obtained. Next, the wavelet transformation is applied to the displacement...
When performing vibration tests on civil engineering structures, it is often unpractical and expensive to use artificial excitation (shakers, drop weights). Ambient excitation on the contrary is freely available (traffic, wind), but it causes other challenges. The ambient input remains unknown and the system identification algorithms have to deal with output-only measurements. The empirical mode decomposition...
