Abstract

This paper details an assessment of three flexural failure ice models for offshore conical structures. Models assessed include the modified Croasdale model, the Ralston model and the recently developed Mayne model. Each model was used to predict global ice loads for selected events observed at the Confederation Bridge. The theoretical loads from each model were compared to the actual measured load for each event. Measured loads were determined through processing data recorded by the bridge instrumentation. The investigation included 22 ice-structure interactions which were considered extreme.
具有极端事件的弯曲破坏模型的评估
本文详细介绍了海上锥形结构的三种弯曲破坏冰模型的评估。评估的模型包括改进的Croasdale模型、Ralston模型和最近开发的Mayne模型。每个模型都用于预测在联邦大桥观测到的选定事件的全球冰荷载。将每个模型的理论载荷与每个事件的实际测量载荷进行比较。通过处理桥梁仪器记录的数据来确定实测荷载。这项调查包括22种被认为是极端的冰结构相互作用。
