2E14 Design of Aluminium and Stainless steel structures
- Department of Steel and Timber Structures
The course will supply students with basic information on material bases, behaviour and design of load bearing civil engineering structures from aluminium alloys and stainless steels.
Expansion of structures made of aluminium alloys and stainless steels during last decades will be demonstrated and advantages perchance drawbacks of using these materials will be discussed.
The first part of the course will be devoted to structures from aluminium alloys. Selection of suitable materials for given structure, material properties and application examples will be provided. Subsequently primary information on design in accordance with Eurocode 9 (Design of aluminium structures) will supply students with view concerning differences with respect to design of steel structures. Heat affected zone softening (HAZ) will be shown and corresponding effect on design. The course will cover design from the view of both ultimate and serviceability limit states, including design of various types of connections. Finally advanced models beyond elastic limit will be demonstrated and further possibilities of design using educational programme TALAT and others will be provided.
The second part of the course will be devoted to structures from stainless steels. Trends in design using stainless steels and recent notable structures will be discussed. Again a survey of general stainless steel materials and those suitable for civil engineering structures will be provided. The information on design will follow Eurocode 3 (General rules - Supplementary rules for stainless steels) and recommendations of Euro Inox. The course will cover design from the view of both ultimate and serviceability limit states, including design of various types of connections. Special attention will be given to erection and installation of stainless steel structures in respect to need of specific treatment, handling and storage of stainless steel elements and structures.
