Results are presented from an experimental program that has been conducted for the purpose of investigating the mechanical behavior of high-strength bolted steel connections assembled with A-320 bolts under probable Alaskan temperatures extremes of -55°F (-48°C) - 75°F (24°C). Extensive analyses are presented for the slip coefficients and slip behavior under cyclic loading for connections assembled with plain steel plates, corrosion resistant painted steel plates, or galvanized steel plates. Also, examinations of plain versus galvanized bolts and the turn-of-the-nut versus calibrated torque wrench methods of insulation are presented. Based on experimental results, recommendations are presented for the optimal design of high-strength bolted steel connections for the Alaskan type climatic environments.
