Abstract

Light gauge cold-formed channel sections are frequently used in portal frame construction for small span agricultural and industrial sheds. A testing program at the University of South Australia has shown that the knee joint currently used in these sheds fails at bending moments well below required design values. An alternative joint construction using multiple Teks screws is being developed and is exhibiting much better performance.

Knee Joints in Cold-formed Channel Portal Frames

Light gauge cold-formed channel sections are frequently used in portal frame construction for small span agricultural and industrial sheds. A testing program at the University of South Australia has shown that the knee joint currently used in these sheds fails at bending moments well below required design values. An alternative joint construction using multiple Teks screws is being developed and is exhibiting much better performance.
