Twelve full-scale studies were used to determine their behavior. The results reveal that the moment resistance values increase in direct proportion to the thickness of the beam. In addition, the ratio of beam thickness ("t") to gusset plate thickness ("t(p)") is critical in calculating rotation capacity, energy dissipation values, and cost-effective design. The ductility of the joint values is also affected by the thickness of the gusset plates. Furthermore, the failure modes of the all-specimens tests show that the gusset plate thickness can be reduced to make the system more cost-effective.eninfo:eu-repo/semantics/closedAccessMoment-Rotation BehaviorCold-Formed SteelScrewed ConnectionBeam/Gusset Plate ThicknessesFailure ModesArticle
