Abstract
This thesis provides a new added mass coefficient for a single degree-of-freedom model of a cylindrical structure submerged in the impulsive zone of a tank that is subject to ground motion. The new added mass coefficient is determined as a function of the diameter of the internal structure. The new added mass coefficient for the internal structure is verified by comparing the resulting motion to a fluid-structure interaction solution obtained with the finite-element method, and a physical experiment. The results of this research show that the new added mass coefficient correlation can be determined by setting an added mass coefficient in the single degree-of-freedom model such that the results show reasonable agreement with the finite-element simulation. The new added mass coefficient is lower than the classical added mass coefficient presented by Fritz because the fluid is allowed to move above and below the ends of the submerged structure.
