Abstract EN
Modal parameters are sensitive indicators of structural damages.
However, these modal parameters are sensitive not only to damage, but also to the environmental variations.
Development of vibration based damage detection methodology which is robust to environmental variation is essentially important for the structural safety.
The present paper utilizes a recently developed modal strain energy decomposition (MSED) method to localize the damage of an offshore structure.
A progress of the present paper is to take the temperature variation into consideration and Monte Carlo simulation is introduced to investigate the effect of temperature variation on the robustness of damage localization.
Numerical study is conducted on an offshore platform structure considering the temperature variation.
Several damage cases, including single and double damage scenarios, are included to investigate the damage localization algorithm.
Results indicate that the MSED algorithm is able to detect the damage despite the temperature variations.
