| Summary: | Offshore structures in waters where ice cover is prevalent from four to nine months a year have been constructed for the last 30 years to extract natural resources and to transport people and goods. Many of these structures are conical or sloped faced in shape, where flexural failure becomes the dominant mode of failure for the ice sheet. This reduces the magnitude of ice structure interaction loads in comparison to other modes of failure. In this particular study, ice interactions with the piers of the Confederation Bridge were examined. Since the 13 km bridge, spanning across the Northumberland Strait between the eastern Canadian provinces of Prince Edward Island and New Brunswick, opened in 1997, the Confederation Bridge Monitoring Program has been instituted to monitor ice interactions with the piers through the installation of video cameras, load sensors, and deformation sensors. Through 15 years of the Monitoring Program, archived video footage have shown that the highest interaction loads recorded on ... |
