Analysis for web crippling behaviour of cold-formed steel members

This paper is concerned with the application of non-linear finite element procedures in the analysis for web crippling behaviour of thin-walled mono-symmetric (lipped channel section) cold-formed steel members subjected to interior one-flange loading conditions. Elasto-plastic large deformation responses of three such members have been obtained using the ADINA finite element program. Flange curling, the gradually increasing separation between …
