Ice Loads on the Confederation Bridge Piers
The bridge crosses the Atlantic Ocean over a stretch of water known as the Northumberland Strait. This particular body of water is well known for the amount of ice that forms on the channel from January to late April of each year, with ice pans measuring up to four kilometers in diameter and one meter thick. Therefore, the piers needed to be designed so that the forces created by the moving ice would not cause the piers to fail, and cause a catastrophic collapse of the bridge structure. However, such a design has never been done before; therefore no design data was available.
The following paper will highlight a comparison of the method used to predict the annual ice loads on the bridge piers versus the actual loads generated from the ice as measured by equipment in the piers.
