This paper aims to study the experimental and analytical behaviour of cold-formed steel (CFS) T-joint members with or without external ring stiff eners under combined axial compression and bending. The parameters varied in the study include the type of T-joints (with and without ring stiff eners), spacing of the stiff eners (100 mm and 200 mm from the central axis of the T-Joint), and thickness of the ring stiff eners (4 mm and 6 mm). The load–defl ection and load-strain behaviour were studied by measuring the overall defl ection of the T-joints and strain using dial gauges and strain indicators, respectively. The load-carrying capacity of the T-joints with external ring stiff eners was compared, and the results of a numerical investigation showed good agreement. An extensive parametric study was carried out for diff erent geometric parameters of the ring stiff ener, chord, and brace member using the FE model to obtain the ultimate strength of the stiff ened T-joints, and strength was also compared and obtained using the published equation. From the results of this investigation, it was found that the T-joints with external ring stiff eners can resist more strength and deformation when compared to the T-joints without external ring stiff eners.
