“…Papers describing the replacement of movable spans (Fisher & Robitaille, 2011) and the kinematics of movable bridges (Byers, 2008;Wallner & Pircher, 2007) are examples of studies for movable bridges in general. For bascule bridges, a brief review of the Chicago-type bascule bridge design (Ecale & Lu 1983) and full-scale testing of procedures for assembling trunnion-hub -girder interactions by Besterfield, Nichani, Kaw, and Eason (2003) are important examples. Other than these examples, there are also some studies on lift bridges, mainly related to construction by Ramey (1983), Griggs (2006) and Zhao, Wang, and Pang (2011).…”

“…In 2000, this effort was followed by integrating a single research problem [3,4] of assembling fulcrums of bascule bridges into the classroom [5]. This research problem had broad-based use in exemplifying multiple concepts such as interference fits, axisymmetric response problems, transformation of strains and stresses, comparison of failure theories, critical crack length aspects, and effect of temperature dependent thermoelastic properties.…”

“…The THG assembly is made by using interference fits 5 between the trunnion and the hub, and the hub and the girder. The procedure 6,7 for assembling THG assemblies involves shrinkfitting the trunnion into the hub and then shrink-fitting the trunnion-hub onto the girder ( Step 1: The trunnion is shrunk by immersing it in a cooled medium such as liquid nitrogen or dry-ice/alcohol mixture.…”

“…To prevent the recurrence of these assembly problems, Florida Department of Transportation (FDOT) decided to conduct an investigation 8 by providing a research grant to the Department of Mechanical Engineering at the University of South Florida. For three years, USF conducted a thermal stress analysis 6,7 of the fulcrum assembly procedure by using analytical 9 , numerical 10 , and experimental techniques 11 .…”
