In the ice-covered oceanic region, the collision between sea ice and offshore structures will occur, causing the crushing failure of ice and the vibration of structures. The vibration can result in fatigue damage of structure and even endanger the crews’ health. It is no doubt that this ice-structure interaction has been noted with great interest by the academic community for a long time and numerous studies have been done through theoretical analysis, experimental statistics and numerical simulation. In this paper, the bond-based Peridynamics method is applied to simulate the interaction between sea ice and wide vertical structures, where sea ice is modeled as elastic-plastic material, with a certain yield condition and failure criterion. Oscillation equation of single-degree-of-freedom is considered to investigate the vibration features of the structure during the interaction process. The damage of ice, ice forces and vibration responses of structure in the duration are obtained through numerical simulation. A parametric investigation is undertaken to identify the key parameters, such as ice thickness, the diameter of structure and relative velocity that trigger the ice crushing, ice forces and vibration responses of the structure. Results indicate that all three parameters have a positive correlation with the overall level of ice force and vibration displacement. Besides, a velocity coefficient is proposed to predict the vibration displacement based on its relation with ice speed.
