Cold-formed austenitic stainless steel channels with unfastened flanges subject to web crippling
Abstract
This research aims to investigate the web crippling strength of cold-formed steel channels fabricated with austenitic stainless steels subject to concentrated transverse forces both experimentally and numerically. The experimental programme is on channel specimens with unfastened flanges and with different web depth to thickness ratios; the tests for channels under both one- and two-flange loading scenarios are covered. For the numerical investigations, detailed nonlinear quasi-static finite element models are used and validated against experimental data. Complementary parametric investigations are then conducted to ascertain the web bearing strengths in terms of various channel sizes, web thicknesses and internal fillet radius. While mechanical properties and material stress-strain shape of different class of stainless steels are different from each other, particularly considering well rounded material behaviour of austenitic steel, no cold-formed stainless steel standard distinguishes between grade of stainless steel, with each standard providing only one equation for different loading scenarios to cover all grades. It is found that the current design equations for stainless steel channels are not reliable to calculate the web bearing strengths of austenitic stainless steel channels and lead to 33% unconservative design. In addition, the web bearing strengths are shown to be higher than those predicted from equations found in the literature for ferritic stainless steel by as much as 34%.
