Seismic Performance of Inclined Moment Connection between Cold-formed Beam-column Joints
In this paper, a combination of laboratory tests and finite element analyses was used to investigate the seismic performance of bolted moment connections between cold-formed steel sections. All structural members such as beams and columns are formed with two lipped C-sections back-to-back; Moment connections between beams and columns are formed with hot-rolled steel gusset plates; [...]

Study on Bending Deformation Behavior of Cold-formed Steel Beams
The cold-formed steel beams are widely used in the low-rise residential buildings. It is difficult to predict the deformation of purlin beams,because of the size,location, type of the loads and the span,bending rigid of the beams etc,.So the deformation of the beam is not well understand now..The deformation behavior of a total of 13 cold-formed [...]
