Secondary Stress within the Structural Frame of DYE-3: 1978-1983.
DEW line ice cap station DYE-3 was moved sideways 210 ft and placed on a new foundation in 1977, then raised 27 ft in 1978. Secondary forces within the structural steel framework were measured in 1978, 1981, 1982, and 1983. The overall level of secondary stresses had increased but through 1983 the c...
