Abstract

The application of Cold-formed Steel (CFS) in construction works increased significantly. Recently this material is commonly used as a non-structural component. However, the research on CFS as a structural component still needs more comprehensive studies. This paper presents the parametric study of three connection types between CFS slab and column panel. It consists of: a) Gusset plate connection only (Isolated Joint Test (IJT)-01), b) Gusset plate with an additional seat angle (IJT-02), and 3) Gusset plate with additional top and seat angles (IJT-03). A T-shaped gusset plate was selected for all three connections. This current study investigates the moment capacity of the connection by combining the gusset plate with an additional top-seat angle. The dimension size of the lipped channel is C12524, and the top-seat angle is L1601607. The gusset plate thickness is 4 mm with M10 bolts. According to the component method, the assumption of elastic behavior is proposed in this paper (BS EN 1993-1-8 and BS EN 1993-1-3). The calculation results for each specimen confirm that IJT-03 is superior to IJT-01 and IJT-02. The failure mode of IJT-03 is predicted to happen at the top angle cleat due to the bending moment.
