Part of: Spatial, Lattice and Tension Structures


Among various existing design rules for circular tubular connections, the AWS rules are compared with the AIJ rules because of differences between the two. Subjects of discussion include accuracy in prediction, effects of size and material properties, premature failures due to local buckling of braces and due to fracture at weld toes, and applications to multi-planar connections, focussing them on the ultimate behavior and design of K-connections for the sake of conciseness. Many points required to enhance the reliability of the AWS rules are suggested.
