Abstrakt:

This research investigates the behaviour of the novel U‐connector used in cold‐formed steel (CFS) truss‐to‐column connection. The novelty is reflected in the specially designed connector geometry and the connection method within the cross‐section of the thin‐walled C‐profile. The U‐connector installed inside the truss‐to‐column connection can be exposed to tensile, compressive and shearing action. The shear behaviour of the U‐connector is thoroughly investigated using laboratory tests. Three different loading scenarios are carried out to evaluate the shear strength of the U‐connector within the C‐profile connection. The detailed analysis is carried out using Digital Image Correlation (DIC) technique for measuring the displacement. The failure modes observed during the experiments are described and analysed. DIC technology is used to accurately identify the failure initiation of each component in the connection. In addition, two different methods for calculating the bearing resistance of the U‐connector and the C‐profile connection are proposed according to recommendations given in the standard EN 1993‐1‐3. These methods aim to provide accurate estimates of the connection's bearing capacity.
