| Abstract: | The intensive vibration of flexible structures induced by continuous crushing of ice indicates the dynamic nature of ice loads and the necessity of taking countermeasures to solve this problem. A systematic approach of structural optimization for improving dynamic ice-structure interaction is presented in this paper on the basis of matrix perturbation and dynamic substructure techniques. The approach and its effect are partially illustrated by the performance of a Bohai jacket platform. |
