05.04: Combined loading of slender stainless steel SHS/RHS members
The presented research shows behaviour of slender stainless steel members loaded by compression and bending which is demonstrated on square and rectangular hollow sections (SHS/RHS) made of austenitic stainless steel. An initial numerical parametric study in FE software Abaqus is given and its results are compared to the existing design procedures and design standard rules. The investigated parameters are mainly the column slenderness, section slenderness, ratio between the applied bending moment and the axial compressive force. The necessity of having additional design rules for stainless steels is firstly demonstrated on the values of interaction factors ky which are significantly higher for stainless steel members due to the material non‐linearity with decreased stiffness even at lower stress levels. As an alternative, the General Method is used for comparison to the Abaqus GMNIA model results. The limitation of the method when used for members of non‐linear material behaviour is shown and a simple and safe modification of global analysis method is suggested.
