Abstract


This paper investigates new bolted and welded beam-to-column connection types on the cold-formed steel sections (CFS) and their behaviors determined using full-scale experiments. This study aimed to analyze the influence of weld/bolt connections based on CFS profile and failure modes to provide the necessary data for improving Eurocode 3. In contrast, the rotation and ductility of a joint of the welded connection are lower than the bolted connection. Thus, the bolted connection exhibits a semi-rigid behavior‒also, the energy dissipation capacity values in the bolted connection are bigger than welded connection. Thus, the bolded connection has a semi-rigid behavior. Also, model failure is determined by the type of connection (bolted and welded). The rotation and ductility of a joint of the welded connection are lower than the bolted connection. Thus, the bolted connection exhibits a semi-rigid behavior‒also, the energy dissipation capacity values in the bolted connection are bigger than welded connection. Furthermore, the specimens of the welded connection have rigid behavior in the failure modes.
