The study addressed the reliability of concrete as a valid construction material for Arctic structures. The focus will be on problems of structural deterioration caused by the loss of durability due to environmental effects, variation in material properties due to extreme temperature, and to abrasive damages or large concentrated stresses due to sea ice.
Completed. An international symposium on this topic was jointly sponsored with the Canadian Center for Mineral and Energy Technology on March 1-2, 1983. Participation was largely from the U.S., U.K., Scandinavia, and Canada. Based on this workshop, a comprehensive project was initiated to look at the punching shear of a large scale, lightweight, heavily reinforced concrete member that would be used on Arctic structures. In addition to MMS, five industry participants provided support for this project.
