The subject of the paper are cold-formed, thin-walled non-standard channel beams with stiffened webs. The local elastic buckling and limit load of the beams subjected topure bending are investigated. This study includes numerical, based on the Finite Element Method and the Finite Strip Method, calculations and actual tests of beams in the laboratory. The presented results give a deep insight into behaviour of such beams and may be used to validate analytical models.
