ABSTRACT

Cold-formed steel (CFS) is a type of steel manufactured at ambient temperature using bending and rolling methods, enabling enhanced precision in shape and sizing. Its adaptability, resilience, and environmental sustainability render it very beneficial for building. Furthermore, its manufacturing method is more energy-efficient than conventional steel production and decreases emissions. Nonetheless, CFS has several limitations, including vulnerability to buckling owing to its slender profile. This research especially examines beam-column constructions with cold-formed steel connections. The paper discusses an experiment utilizing the sub-assemblage frame test method to improve the connection's resistance by emphasizing on rectangular gusset plates and the top-seat angle. The results demonstrated that the upper beam flange was the most susceptible, resulting in lateral-torsional buckling and a reduction in the applied load. Graphs were employed to examine the load and deflection data, with maximum load and deflection values documented for each specimen. RGFC-200 exhibits a maximum load that is 44.98% more than that of RG-200, whilst RGFC-250 has a maximum load that is 35.46% superior than RG-250. RGFC-250 has a maximum load capacity that surpasses RGFC-200 by 16.7%.
