Abstract: This thesis studies the possibility of designing a full aluminum deck which would be economically interesting in order to compete with the use of concrete slab and wood for bridge decks. The requirements for this project are that the new concept has a span of 15 meters, can be built in a factory and can be assembled in the field. This thesis is part of the Quebec aluminum development strategy (SQDA 2015-2025) and is done in partnership with the ministry of Transportation, of durable Mobility and of transport Electrification (MTMDET). Having rejected the possibility of a 15 meters long aluminum deck without any clamp system between panels and entirely made in Quebec, an innovating concept has been proposed using only extrusion with a circumscribed diameter lower than 460 mm (18 inches). Seeking to validate the new concept with the CAN/CSA S6-2014 code and by the finite element method, it has been realized that chapter 17 of this code, related to aluminum structures, is very conservative and sometimes incomplete. Consequently, new methods have been proposed to have access to truck load fractions or to effective length of an aluminum deck. An economic analysis has been made after having studied the technical considerations. It focused on production costs of an aluminum deck and a comparison with the production cost of a concrete slab or a wooden deck. Finally, considering the results, a final conception has been proposed which qualifies for the code and is economically viable.
