Sažetak
In this study, an innovative fabricated angle bracket connection for joining cold‐formed steel structures is presented and investigated. The innovation lies in the especially designed and manufactured angle bracket and in the method of connecting the angle bracket for the C‐profile using clinch pressing. This novel angle bracket can be used to connect cold‐formed steel elements such as beam trusses at the ends of the chords or for anchoring the column base. Five specimens were fabricated and experimentally tested under monotonic tensile loading until failure. A specific tool was developed to properly hold C‐ profiles. Three displacement measurement procedures were performed, and the appropriate method was used to analyse the test results. The main failure mech‐ anism of the angle bracket connection determined by the tests was pull‐ through of the M12 bolt, whose resistance is compared with the calculated values according to the AISI S100‐16 and EN 1993‐ 1‐3 standards. There was no bearing failure in the innovative connection between the C‐profile and the angle bracket, which indicates an increase in the bearing capacity of the connection
