AbstractIce interactions with the Confederation Bridge for the winters 2008, 2009 and 2010 have been studied. Tilt data from piers P23 and P24 in response to ice and wind actions were recorded by a data acquisition system. Video records of ice interactions with pier P23 and overall ice conditions adjacent to piers P23 and P24 allowed ice conditions and interaction processes to be related to tilt measurements. Wind data were also analysed to correct for the tilt caused by wind actions on the bridge. An ice loading scenario of slow build up of ice force on a pier due to the action of current and wind on a large ice floe was identified. In one instance this resulted in a maximum force of about 4 MN being generated on simultaneously on each of piers P23 and P24.
