Fatigue of welded details made of duplex stainless steel (Bridge construction made in duplex stainless steel)
The ability of duplex stainless steel to be used in a both economic and efficient way for bridge construction in aggressive environment has been investigated in the scope of an international research project funded by the EU research programme RFCS (Research Fund for Coal and Steel). As the behaviour of duplex steels highly depends on the material properties efforts have been put in the investigation of the material, fabrication and the effect of the fabrication on the material. The corresponding paper to this abstract is related to the fatigue behaviour of critical constructional details met in welded bridges. While both EN1993-2 and EN1993-1-9 contain the fatigue design criteria for welded structural details made of carbon steel, supplementary rules for stainless steel are given in the EN1993-1-4. Although the criteria are extended to stainless steel grades, they are not applicable to all welded structural details met in the bridge construction. Thus, a re-evaluation of available test data for stainless/duplex steel specimens has been made, missing fatigue tests have been performed and the results have finally been compared to the detail categories for C-steels, see Table 1.
