An Experimental Method for Evaluating the Overturn Moment of Submerged Structures

Young-Jun You, Youn-Ju Jeong, and Min-Su Park
Abstract—Experiments are a good method to evaluate the capacity and performance of a structure, and a numerical analysis tool is a good back-up tool for making the experiment results more reliable in predicting the performance of the structure with various parameters. However, designers sometimes face practical problems such as experiment constraints, expenses, or realization of a real situation with scaled down models. This paper focuses on how to easily quantify the resistant capacity against overturning of submerged structures by experiment. The overturning resistance of a submerged structure in the experiment was acquired by an opposite concept in which a specimen was not placed on the bottom but dangled from the top. A numerical analysis was used to complement evaluation of the overturning moment. Overturning resistant capacity of submerged structures by waves was acquired easily from this method.

Index Terms—Overturning moment, substructure, offshore wind power, numerical analysis.
