This paper presents investigation on cold-formed steel (CFS) beam-to-column
moment-resisting (MR) bolted connections with high energy dissipation capacity
suitable for seismic areas. Bolting friction-slip mechanism of the introduced CFS
MR connection is developed as its main seismic energy dissipation fuse aiming
to postpone or eliminate local buckling and yielding in the CFS MR connections.
Finite Element (FE) modelling techniques are employed to effectively simulate
the connections with an activated friction-slip mechanism. Hysteretic energy
dissipation response of the connections with circular bolting (CB) arrangement
designed to slip at 0.5Mp are presented. Based on the obtained FE results, fullscale physical tests on the CB connections have been performed under cyclic
loading. Both the FE and the test CB connections comprised double back-to-back segmental-flange beams of 2, 4 and 6mm thicknesses. The results show that the bolting friction-slip mechanism developed for the CB connections can effectively delay local buckling and yielding in the CFS beams of as thin as 2 mm
