摘要

Frame corner joints built up from cold-formed C-profiles and mechanical fasteners (metric bolts and self-drilling screws) are investigated by experimental program. 26 specimens with different profile and connection parameters are studied. The behaviour is analysed by the measured moment-rotation relationship of the joints. The experienced behaviour is combined phenomena of different local instabilities of the profiles and the connection performance. On the bases of the governing phenomenon three behaviour modes of the joints are determined and explained in the paper.
