Full-scale, high frequency data obtained from an in-situ monitoring program of the Confederation Bridge is used for the calculation of ice action on the conical structure. The ice pressure distribution analysis involved identification of events, identification of sector activations, identification of pressure peaks, and their distribution on different sectors of Ice Force Panels. Ice pressure and its correlation between different sectors of pressure panel are also determined. Some stalled event are analysed to study the effectiveness of pressure panel to record sustained pressure. Because of higher percentage of bad sectors in columns than in rows, the vertical (along the slope) distribution of ice pressure is comparatively better defined than the horizontal (along the circumference) distribution of ice pressure. The peak pressures are found to be concentrated on the panels at the water-line and the pressure goes on reducing along the slope above and below the water-line. Adjacent panel sectors and sectors along a particular row are found to have better correlation with each other. This distribution of pressure on conical pier is an important output obtained from the data that was initially not given the priority that it deserved.
