State of the art review of the stability and welding of aluminium alloy elements

Iako je aluminij vec dugo prisutan konstrukcijski materijal, uporaba mu nije u skladu s dobrobitima koje se ostvaruju njegovom primjenom. Slican je celiku, no između njih postoje znacajne razlike kako u proizvodnji, tako i u fizikalnim i mehanickim svojstvima. Upravo iz tih razlika proizlaze posebnosti u podrucjima stabilnosti dijelova poprecnih presjeka i konstrukcijskih elemenata te u podrucjima zavara. Ta polja jos uvijek predstavljaju aktivna podrucja istraživanja zbog velikog broja legura, obrada i oblika poprecnih presjeka profila.

Applications of aluminium alloys in civil engineering

Although aluminium is a long known structural material, its use is not in accordance with the benefits achieved by its implementation. There are several reasons for such an adverse state. Those that stand out are the late development of a regulative framework for the design of structures, and still the need for improvement, lack of knowledge on application examples and not stressed enough potential areas of use. However, positive trends are present and aluminium alloys are competitive, especially if their positive properties can be utilized and negative properties diminished though purpose oriented design approach. Given examples present good application utilization of aluminium alloys characteristics, and shown new application research can provide directions for further expansion of competitiveness. Structural uses are grouped in suitable areas of application and put into local and global context.
