Abstract: A communication to the 1970 Symposium described two field installations designed to measure dynamic ice forces on bridge piers. In April 1971, both installations were subjected to repeated impacts from ice floes of varying sizes. Synchronization of force recording and movie photography at one site enabled force fluctuations to be compared with the nature of the ice failure. Peak instantaneous forces were generally several times larger than mean forces averaged over durations in the order of one second. Peak unit pressures on a vertical pier appear to have been comparable with ice strength in compression.
