THE INTERACTION OF ICE AND COMPLIANT VERTICAL NARROW STRUCTURE

摘要

The problem of ice induced vibrations on vertical structures has been widely studied in the world, but the research results are still far to be applied in practical engineering. To explore the mechanism that controls the procedure of ice induced vibration, a series of model tests were performed. The interaction of ice and structure was found to be the control mechanism in the model test study. Intermittent ductile-brittle crushing is the most important characteristic in the process of interaction. Based on this important phenomenon, a new concept — interaction coefficient — was set up in this paper. This parameter directly reflects the interaction level of ice and structure.
