Abstract

The dynamic ice forces on a structure with vertical wall and the corresponding responses of the structure are predicted. The structure was simplified as a 1-degree-of freedom system which consists of spring-mass-damper. Ice was divided into two parts : near filed and far field. In the near field, ice sheet moves with constant speed. The results obtained from the numerical simulation using the model and the experiment of indentation with stiff and flexible structures are compared. The comparisons show that the model can predict the behavior of structure and ice load with accuracy.

평탄빙과 수직구조물이 상호작용 하는 경우의 구조물의 동적거동과 빙하중 추정을 하였다. 구조물의 형태는 수직구조물이고 얼음의 파괴형태는 분쇄파괴로 가정하였다. 평탄빙은 구조물과 접촉하여 분쇄파괴가 일어나는 접촉부위와 탄성변형을 하는 외곽부위로 나누었으며, 구조물은 스프링-질량-감쇄로 구성된 1자유도계로 치환하였다. 강성이 큰 구조물과 작은 구조물에 대하여 제시된 모델에 의한 계산결과와 실험결과를 비교하였다. 비교결과는 본 모델이 빙하중과 구조물의 거동추정을 정도있게 할 수 있다는 것을 보여주었다.
