Alaska Air National Guard Composite Building

Home and History

This project was designed for the Alaska Air National Guard located on Eielson Air Force Base. It includes an aircraft hangar and several associated maintenance shops, offices, and support facilities. The structural aspects most notable for this structure are the 190 feet clear span built-up girders used to resist vertical loadings from dead loads, snow loads, equipment loads, and seismic and wind loadings. The design of these girders is thoroughly state of the art. Extremely large plate elements were required to build these structural elements, and as such, quality control during construction was very important. The design of weldments required special attention to assure that stress concentrations and laminar tearing phenomena are properly accounted for. Diagonal bracing necessary to prevent lateral torsional buckling effects were incorporated into the design.

This project also included a waste oil disposal system. The design complies with the EPA regulations for the design and installation of underground storage tanks including double wall tank construction, double wall piping, and annular space leak detection.
