ULTIMATE CAPACITY EQUATIONS FOR TUBULAR JOINTS

A total of 137 ultimate strength tests on simple T,Y,DT and K tubular joints is used as a basis for development of new ultimate capacity formulas. The data are taken from a variety of sources and only relatively large geometries are considered. Axial tension, axial compression, in-plane bending and out-of plane bending loads are represented. The failure condition is taken as the minimum of either maximum load, first crack load or load at an excessive deformation limit. Several formulas are recommended to predict the capacity of the different joint and load types. The accuracy of these formulas is then studied in a statistical manner. Predictions of past and present API RP 2A formulas are compared to the same data base. It is found that the new equations are more consistent in their level of prediction and result in less scatter. The new equations are also relatively simple in format.
