| Abstract | Web crippling behaviour of cold-formed high strength steel tubular sections under oneflange loading conditions is studied in this paper. A total of 29 tests was conducted on square and rectangular hollow sections of high strength steel with nominal 0.2% proof stresses of 700 and 900 MPa. The tests were conducted under End-One-Flange and Interior-One-Flange loading conditions. Finite element (FE) models were developed and validated against the experimental results. On validation of the FE models, a parametric study comprised 112 FE analyses was performed using the validated models and obtained numerical data over a wider range of web slenderness ratio. The web crippling strengths obtained from experimental and numerical investigations were compared with the nominal strengths calculated using the current North American, Australian/New Zealand and European specifications for cold-formed steel structures. Web crippling design rules based on Direct Strength Method are proposed for cold-formed high strength steel tubular sections. The reliability of the proposed design rules has been assessed through reliability analysis. |
