University of Alaska Building 7 Report

Figure 3.6 Section view at Floor 13 of Column 79 and girder A2001 seated beam connection, which shows stiffener plates on girder A2001 (Data from Frankel Steel Limited, 1985, Drawing 9114; figure prepared by Brookman, 2012). 3.2.2 Girder A2001 Web Stiffeners Prevent Flange Failure and Girder Walk-off A separate model was generated to determine what would happen if girder A2001 were able to somehow move past the Column 79 western side plate. This model removed the side plate protrusion that we found in our previous analysis would interfere with the girder’s lateral travel. The results are shown in Figures 3.7 and 3.8. To perform this analysis, the coefficient of thermal expansion of the steel used for beams K3004, C3004, B3004, and A3004 was increased by approximately 40% to 11.5 x 10-6 in/in/°F 80
