Abstract: Comparison of the formulae taken from 5 Eurocode parts EN 1993-1-1 [1], EN 1993-1-3 [2], EN 1993-1-5 [3], EN 1999-1-1 [4] and EN 1999-1-4 [5] valid for calculation of resistance of I-section under bending moment – shear force interaction. An attempt to create basis for harmonization of different rules used in EN 1993 Design of steel structures and EN 1999 Design of aluminium structures. The rules concerning verification of metal I-section resistance under bending moment – shear force interaction could be simplified and harmonized in the above five parts of metal Eurocodes. Eurocodes interaction formulae are compared with formulae given in Czech [6] and Slovak [7] standards and interaction formulae given in [13 – 18]. Results of large parametric study authors published in papers [8 – 12, 19].The resistance of the I-section to interaction of bending and torsion internal forces [20 – 22] which is missing in the current Eurocodes is analyzed too. New approach is proposed.

Abstract: The paper deals with the applications of aluminium alloys in the main structures used in the Offshore Industry. The reasons why aluminium and its alloys are the suitable materials for this kind of applications are clearly identified. After mentioning the appropriate standards and design rules, some important examples, like helicopter decks, gangways and living quarters, are illustrated in details. An overview on the typical connecting systems of aluminium alloys commonly used for the offshore technology is presented.

Abstract: Since INALCO 2013, the two main North American aluminum structural design codes – the Canadian Standards Association’s (CSA) S157 Strength Design in Aluminum and the Aluminum Association’s Specification for Aluminum Structures – have undergone significant changes. S157’s 2015 edition is the first significant revision of the Canadian aluminum structural standard since 2005, and the 2015 update of the Specification for Aluminum Structures is the first since 2010. This paper addresses the specific changes and their trends, viewed from a larger perspective to anticipate the future direction of these codes.

Abstract: The effect of severe plastic deformation by ECAP process on the microstructures and mechanical properties of the aluminium alloy EN AW 6082 produced by cold extrusion is investigated. In both states were evaluated the structural changes by light microscopy, the analysis particles in structures, by X-ray diffraction (XRD) in transmission mode by synchrotron radiation and mechanical properties. Severe plastic deformation leads to strengthening of investigated EN AW 6082 alloy but on the other hand the plasticity of ECAP-ed alloy decreases.
