000012730 520__ $$2eng$$aDouble-bay portal frames have several advantages over two single portal frames positioned adjacent to each other, however the connecting system can be a challenge, especially if the portal frame is formed from single cold-formed channels. The portal frames described in this paper consists of a column and two rafter members, formed from single cold-formed channels sections, and bolted back-to-back at the eaves joint through a gusset plate. Tests were performed to evaluate the structural performance of the eaves region of double-bay portal frames. The eaves region represents the distance from the point of maximum moment (eaves joint) to the point of zero moment (contraflexure) in the rafters and columns respectively. The structures failed by local buckling in the compression flange and web of the rafters, outside the joints. The moment-curvature graphs proved that plasticity could not be achieved in these connections.
