This paper describes 24 tests performed on welded specimens made of 3 stainless steel grades: EN 1.4307 (304L) and EN 1.4404 (316L) austenitic grades and EN 1.4062 duplex grade. For each grade, tests were carried out parallel to the weld and along the transverse direction. The austenitic grades were welded using GMAW (MAG), while the duplex grades were welded using Gas Metal Arc Welding (GMAW) and Gas Tungsten Arc Welding (GTAW or TIG). After failure, the fracture surfaces were measured using Digital Image Correlation (DIC) and compared to measurements before testing. The results were compared to 70 experiments on welded stainless steel samples, gathered from the literature. A relatively high scatter was found among the different sources as well as differences between grades and loading directions. A reliability study was then performed in agreement with EN 1990EN :2002 Annex D on the complete experimental data pool and recommendations for the correlation factor βw are then provided.

“…An image processing software correlates the deformed shape of each speckle to the un-deformed one for derivation of the entire strain field [63]. This technique was at first exclusively used in material sciences, but lately is also becoming popular in structural engineering [65,66]. Presently, the processing of the measured data is performed using the virtual fields method (VFM) [67,68].…”

Fatigue is mostly the governing design criterion in girder steel bridges due to the presence of critical welded details. In this research, the hot spot stresses in welded cruciform duplex stainless steel joints are measured experimentally using digital image correlation as well as traditional strain gauges. They are also computed via FEM. The deduced fatigue lives are then compared to each other as well as to small-scale cyclic test results and to a series of literature data on similar welded details. The comparison highlights very consistent results and demonstrates applicability of the hot spot stress method to welded duplex details.

“…Stainless steel plate girders generally carry large transverse loads and typically involve highly slender webs to achieve the efficiency in material use, which make them particularly susceptible to shear buckling. There exist comprehensive previous research into the structural response and design of stainless steel plate girders at room temperature [1][2][3][4][5][6][7][8]. However, the research into the behaviour and design of stainless steel plate girders in fire is very scarce.…”
