Abstract: A study was initiated to determine the adfreeze bond strength between steel pipe piles and freshwater ice as a function of temperature. Tests were conducted at an average strain rate of 1. 5 multiplied by 10** minus **5 sec** minus **1 over a temperature range from minus 51 degree F ( minus 46 degree C) to plus 30 degree F ( minus 1 degree C). Adfreeze strength values ranged from 236 psi (1626 kPa) to 41 psi (282 kPa), respectively. From the data collected, a linear expression has been derived that predicts the adfreeze strength as a function of temperature for high loading rates. The data is then compared to results obtained by other investigators.
