Abstract
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.
Highlights
First significant applications of aluminium alloys in civil engineering emerged in the first half of the 20th century, primarily related to bridge engineering
According to the European aluminium association [14] the portion of secondary aluminium in total production is in constant rise, and in Europe in 2011 it was recorded at 48 %
Croatia, the authors’ country, can be associated to such conditions. In accordance with these claims, the purpose of this paper is to provide an overview of aluminium alloys application possibilities in civil engineering, to present its advantages, shortcomings, Applications of aluminium alloys in civil engineering and current application expansion research
Summary
First significant applications of aluminium alloys in civil engineering emerged in the first half of the 20th century, primarily related to bridge engineering. The combination of a relatively high strength to weight ratio, increased durability and availability in numerous shapes, make aluminium alloys an excellent choice for a wide spectre of civil engineering applications The reasons for such a late development of aluminium as a construction material, and an additional reason for the delay in national technical regulation backup, are [3, 4]: lack of knowledge on its Tehnički vjesnik 24, 5(2017), 1609-1618 possibilities; relatively complex design procedures; relatively expensive production procedure of primary aluminium; not enough recognition of similar achievements in the world. Examples of Croatian practice in aluminium alloys implementations can provide backup for further improvement in local context, and more importantly encourage application expansion - they identify current utilization level
