Abstract

Cold-formed steel (CFS) have been widely used in different structural systems in residential and non-residential construction, especially roof structures due to many advantages. Firstly, no heat is used to form the sections unlike hot-rolled steel. Secondly, several steel thicknesses are offered to accommodate a wide range of structural and non-structural purposes. Researchers have recently searched in the usage of CFS sections, and their research showed an improvement in stiffness and strength of these sections. Therefore, the purpose of this search is to analyze and conduct the behaviour of lipped single and double channel back-to-back CFS sections with edge-stiffened hole. The built-up section attached with self-taping screws under axial compression load. The main focus of this search is to enhance comprehension of the axial behaviour of the simply supported lipped CFS channel sections by analyzing and conducting the behaviour of pinned end condition CFS columns under the effect of static displacement loading till failure and to conduct the verification of the previous finite element modelling. Additionally, this research, focus on determining how the properties of section affect the behaviour and axial strength of lipped CFS column sections and to develop the fundamental parameters and the numerical criteria needed for the non-linear analysis to model lipped CFS column sections.
