Abstract

Using aluminium for bridge deck was firstly in 1933 in U.S.A, in Egypt it is very interested for constructing aluminium bridge. The use of Aluminium alloys for constructing bridges and bridge decks has much to offer because of their light weight, excellent corrosion resistance. Some of the aluminum alloys that used for bridges are 5086-H116, 6061-T651, 6061-T6 and 6063-T6 as given in AAHSTO. In this research aluminum bridges will be studied. Structural analysis, design, and comparison between two bridges having the same geometric dimensions are introduced. The first bridge consists of steel girders and concrete deck slab. The second one consists of aluminum girders and aluminium deck. the Loads and the design of the two bridges are according to (AASHTO LRFD Bridge). It is concluded that Aluminium Bridge can compete the composite one because of its excellent corrosion resistance and light weight of super structure. The aluminuim saves about 82% from the weight of superstructures
