The behaviour of stainless steel open-section slender members subjected to compression and bending has been examined in a few previous studies. Burgan et al. [13] and Zheng et al. [14] reported tests

Welded joint strength depends on the correlation factor , which should be taken 1.0 for all stainless-steel families (according to Eurocode 3 (EN 1993(EN -1-4, 2006). The aim of this study is to investigate the strength and failure mode of the welded stainless-steel joints to determine the value of the correlation factor for austenitic grade EN 1.4301 based on experiments. The experiments investigation consists of tensile tests of two plates (15 mm thick) connected by four longitudinal fillet welds. The load was applied parallel to the weld causing only shear stress in the fillet weld. Every specimen was tested to investigate the strength, strain and failure mode.

The interaction between axial compression and major axis bending of welded stainless steel columns is being investigated at the Czech Technical University in Prague. This paper describes numerical modeling of welded stainless steel I-profile members loaded by a combined load (axial force and bending moment). The detailed finite element (FE) models were developed in software ABAQUS and subsequently validated against test results to simulate the interactive behavior and predict the ultimate capacity. The initial geometric imperfection modes, and amplitudes (global and local), and residual stress were considered to enhance the models accuracy. Material tensile coupon tests were also conducted. The aim of this work is to investigate the current design procedures for stainless steel beam-column members and compare them to the numerical results.

<p>Stainless steel beam-columns were experimentally and numerically investigated in this study. All members were subjected to compression and major axis bending induced by an eccentricity of the compressive load. The loading eccentricities for the tests varied to provide a wide range of bending moment-to-axial load ratios. The experimental program covers ordinary-welded and laser-welded I-section specimens made of stainless steel. Material tensile coupon tests and initial geometric imperfection measurements are also described in detail. Measurements of initial imperfections were performed using two different methods, using a mechanical dial and laser scanning. The test results were subsequently used for a validation of a finite element (FE) model, developed in ABAQUS software to replicate the beam-column behaviour. The accuracy of the models with the two combinations of local and global imperfections were evaluated by comparison with the test results.</p>
