This paper deals with the structural behaviour of a cold-formed steel (CFS) structural frame subjected to lateral loading. The study involves the investigation of structural behaviour via an experiment programme and numerical investigation conducted on a structural frame using a cold-formed channel section constructed in a steel factory. The structural frame comprised columns, beams, a base plate, and its connection The section for the column consisted of a back-to-back channel section positioned and cold-formed. Section used for columns provided with and without lips. The section used for the beam is provided with a single channel section with and without lips. The numerical investigation was conducted using a finite element analysis procedure with the FEA software ANSYS 16.2 workbench. Through these investigations, a parameter study was conducted. Some important influencing factors, such as load-carrying capacity, stiffness, and the load– deflection relationship, were evaluated and discussed. From the result analysis, the structural frame made with a lipped channel section experienced high load carrying capacity and high stiffness compared with the other models considered.
