Abstract:

© 2016 Taylor & Francis Group, London. Stainless steel is increasingly used as a construction material in a range of engineering applications. Significant progress in the development of structural design guidance has been made in recent years. However, not much attention has been given to the behaviour of members subjected to torsion or combined torsion plus bending. This paper describes a preliminary study of the structural behaviour of laser welded stainless steel members subjected to these kind of loads. First of all, a brief review of the current international design standards for (stainless) steel members submitted to torsion and combined torsion plus bending is made. Thereupon, previous experimental studies on members submitted to combined torsion plus bending are summarised. A finite element model of an austenitic laser welded I section is then presented. The results of the aforementioned experiments and the numerical model are then employed to assess the current codified design provisions, of which the shortcomings are highlighted.
