2009) also investigated single span cold formed steel purlins that were connected using gusset plates.
Connections with 10 mm thick gusset plates and 50 mm chamfers showed similar behaviour to those with 16 mm thick gusset plates but without chamfers.
The lateral torsional buckling of gusset plates was found to range from 48% to 77% and the maximum flexural failure in the connected members was found to be 84% of the moment capacity of the connected members.
Typical failure modes for connections using gusset plates are the same as in beam-to-beam connections: local buckling in beam, column sections and gusset plate, elongation of boltholes.
Eight specimens were with gusset plates and the other two were connected without them (using hinged connections) (Fig.
There is a wide variety of techniques to connect cold formed sections using gusset plates, rivets, self-drilling screws, bolts, mechanical clinches or welds;
beam and column web (2), gusset plate (3) in bearing;
the thickness, shape and geometry of the gusset plate and angles;
