Abstract
Ice forces on offshore structures are often the primary design load condition and it is therefore important that they be understood, and can be predicted accurately. During the design of piers of the Confederation Bridge, various design parameters including ice velocity, ice thickness, rubble height, ride up and ridge keel properties were considered in the assessment of ice action. To study the relationship between design models and reality using the full-scale data, various monitoring programs were initiated at the Confederation Bridge. One of the major projects includes continuous measurement of ice forces on piers P31 and P32. During continuous fourteen years of monitoring, a vast volume of data has been generated from instrumentation system at the piers and management of instrument data is one of the prime objectives of this research. The ice load derived from instrument data and event information and failure observations obtained from ice video analysis has enable study of the relationship between loads at adjacent piers, and also the relationship between various ice parameters including: ice thickness, ice velocity, keel depth, interaction height, presence of rubble or ride-up and their effect on ice actions. The study has also allowed comparing and verifying the results with the existing models.
