Abstract	This thesis investigates the structural response of an "IACS polar class" large grillage structure to progressive damage loads from ice. The "IACS polar class" design scenario is a static "glancing" load. It was desired to know if the structure responded differently to dynamic progressive loads, than it did to static loads. An explicit nonlinear numerical model was created. This numerical model was validated against full-scale experiments involving an "IACS polar class" large grillage structure. Eight progressive damage load scenarios were tested using the numerical model. In addition, strategically placed static loads were tested in order to provide a basis for comparison between the dynamic and static structural responses. It was found that the large grillage's structural capacity to withstand dynamic progressive damage loads was generally less than its capacity to withstand static loads. Further, the structural mechanisms behind this decrease in structural capacity were identified.
