The use of stainless steel for structural purposes has recently generated great interest due to its excellent corrosion resistance, ease of maintenance and attractive surface finish. Therefore, as demand increases, the range of structural products is growing and new manufacturing processes and design procedures for this material are being developed. Currently, there is very little experimental data on laser-welded stainless steel members and their design is not included in current design standards. Therefore, the torsional behaviour and resistance of laser-welded I-section members loaded by combined compression and major-axis bending have been investigated in the present study through physical laboratory experiments and numerical modelling. The experimental programme adopted seven beam-columns specimens made of austenitic stainless steel grade EN 1.4301 (AISIS 403L) including initial geometric imperfection measurements and tensile material tests. The test results were subsequently used for validation of a finite element model, developed in ABAQUS software to replicate the beam-column behaviour. The accuracy of the models was evaluated by comparison with the test results.
