Ultimate strength of tubular joints: Chord stress effects
Conference

OSTI ID:6371357
The results of ten tests on large scale circular tubular joints designed to investigate chord stress effects are presented and discussed. Axial, in-plane bending, and out-of-plane bending loads were applied to the branch members of the double-tee specimens, in combination with compressive axial chord loads and chord moments. The results are compared with the previous test work that has been used to develop offshore specifications. It is found that current design equations do not adequately predict chord stress effects on joint strength. New design equations are recommended that better reflect the effect of chord stress on ultimate tubular joint strength.
