Distortional buckling of stiffeners in stainless steel profiled sheeting
Result description
The research presents a numerical study of compressed stainless steel cold-formed thin-walled plates with an intermediate stiffener as is common for flanges of profiled sheeting. The numerical model was validated on tests from literature. These test results were substantially extended by a parametric study to cover the whole slenderness range and common geometries of stiffeners. As stainless steel material exhibits more nonlinear stress-strain behaviour than carbon steels, the results of the numerical study also shown significant deviation of the resistance which is contributed to the material non-linearity. The distortional buckling curve for stainless steel was lower for the whole slenderness range and a modified design procedure was therefore proposed.
