氷盤の衝突による海洋構造物の動的相互作用

Among the various offshore structures which are needed for the development of resources in ice covered seas, columnar structures were selected for the study on the oscillating phenomenon caused by ice floe and the dynamic response caused by earthquake. This research was performed by the model test and numerical analysis. It is aimed to propose the ice load evaluation method for the design of ice resistant structures by considering the dynamic interaction between structure and ice floe. The suitability of using the urea model ice, ratcheting phenomenon, maximum ice load and dynamic behavior of structure are presented in this paper.
