Paper presented at the Offshore Technology Conference, May 2–5, 2005
Paper Number: OTC-17310-MS
... Abstract The development of the new API RP2A (22 nd Edition) parametric static strength prediction equations for planar circular hollow section (CHS) tubular joints is described. Prediction equations are presented for brace axial, brace in-plane bending, and brace out-of-plane bending loads...

... and the boundary conditions that are not possible with physical testing (Pecknold 2000, 01, 02, 05). The Task Group also evaluated and upgraded the tubular joint fatigue design procedures. The welded joint X and X' fatigue design curves in the RP 2A Editions 11 thru 21 have been replaced by a basic SN curve...

... Abstract A Joint industry project (JIP) commenced in 1993'" to develop a design manual for tubular joints which are strengthened or repaired through chord grout-filling. This project has been funded by five oil companies and two regulatory bodies. The project has comprised the conduct of over...
