Application and Research Progress of Aluminum Alloy Bridge Decks

Abstract

In order to increase live-load carrying capacity and life of bridges, aluminum alloy bridge decks have been widely used in bridge structures for more than 70 years because of the features of high strength-to-weight ratio, excellent corrosion resistance, ease of fabrication and recovery, rapid construction, maintenance-free and cost effective. First, this paper provides in detail the advantages of aluminum alloy bridge decks and the main areas of aluminum alloy applications in bridges can also be pointed out. Then, a brief overview of typical application examples and structural shapes of aluminum alloy bridge decks are introduced. At the same time, a state-of-the-art review on the researches of aluminum alloy bridge decks, related to static behaviors, fatigue properties, dynamic responses, structural systems and cost effective, is presented. Finally, the perspectives of research and development on aluminum alloy bridge decks are discussed.
