Experimental investigation on cold-formed steel structural frame made with lipped channel column and beam elements subjected to lateral loading

ABSTRACT

This study examines the structural performance of a cold-formed steel (CFS) structural frame subjected to lateral loading. An experimental investigation was conducted on cold-formed steel frame. Structural building frames made of cold-formed steel structural members. The structural members (beams and columns) were selected for building the structural frame on the basis of optimized design considering factors such as ease of availability of section and adequate testing conditions. In this way, the channel section is used for columns provided with and without lips. Parameters such as load-carrying capacity, stiffness, and the load– deflection relationship were examined. Based on the results and discussion, the structural frame made with a lipped channel section was found to have high load carrying capacity and high stiffness compared with the other models.
