Abstract
Being exposed to huge waves, repetitive wetting and drying as well as vessel collisions, members that are located in the splash zone of offshore platforms are prone to damage and failure. Providing the possibility of identifying and repairing these damages at an early stage, establishing a concise structural health monitoring system for these structures is of a great importance. The modal strain energy-based Stubbs index is one of the most successful vibrational methods for structural damage identification. In recent years, some modifications have been made on this method, one of which is considering natural frequencies for damage localization. By examining the original Stubbs index and an existing modified index, in this paper, a novel damage index is proposed to increase the accuracy of damage localization. Comparing the results of the Stubbs, IMSE (Improved Modal Strain Energy), and the new indices for damage localization in Foroozan platform which is located in Iran and Saudi Arabia water border in the Persian Gulf, this research shows that this novel method has been able to identify the location of hypothetical damage in the structure with higher accuracy. Also, single and multiple damages, with low and high severity, were predicted with appropriate accuracy by this method.
