Bending-shear interaction of cold-formed stainless steel lipped channel sections

• Bending-shear interaction of stainless steel lipped channels was investigated. FE models were developed for shear, bending, and behaviours. Sections with aspect ratios 1.5 2.0 behave under bending-shear interaction. Codified provisions are too conservative a higher level applied shear force. Proposed equations provide accurate consistent predictions. The response cold-formed channel sections has been given inadequate attention in the past. Therefore, this paper investigates bending behaviour using numerical studies. Finite element (FE) validated against experimental results found literature three-point four-point loading tests both steel. elaborated used comprehensive parametric study that conducted comprising 60 simulations five different to response. Another 12 analysed it is subjected while there no effect observed other ratios. Eurocode 3 American specifications then evaluated results. These design be revised proposed aiming better prediction accuracy. Further, statistical evaluation suggest improved
