  Damage Identification in Offshore Structures Using Wavelet Transform of Space Domain Signal
  Author(s): Hamid R Ghafouri and Samira Mirzavand*
  
  Large structures such as bridges, towers, offshore platforms are designed to be used over a long-time period. How- ever, due to the unpredictable and out-of-control events, structural damages occur prematurely. Poor performance or failure of these structures will lead to irreparable impacts. To avoid these losses, engineers always look for methods to detect damages in structures in early stages of occurrence and to reveal their remaining life at the lowest cost. Thus developing a method for detecting system defects is a vital step. One of the main issues in damage detection methods is to seek some damage indexes that are sensitive to structural damage. In this research, a method is developed based on wavelet transform of structural responses and a good index for damage detection in offshore platforms is proposed. Structural data obtained from modal and time-history analysis of a fixed.. Read More»
