AbstractIt is often assumed in calculations of maximum ice pressures against structures that the crushing strength of ice is 400 psi. A model study was undertaken to determine if ice could sustain this stress when loaded in a manner similar to that which would be associated with piers. Columnar-grained ice blocks about 5 in. thick and 24 in. in diameter, with the long direction of the grain perpendicular to the face of the block, were used in the study. The load simulating the pier situation was applied to the edge of the block perpendicular to the long direction of the columns. It was observed that, with this geometry of loading, ice could sustain a stress of 400 psi for periods exceeding two days without failing.
