ULTIMATE STRENGTH OF TUBULAR JOINTS

Tubular joint ultimate strength equations that are helpful for offshore platform design are presented. The formulae are based on data from 346 joint tests. They are easy to use and cover more joint configurations than present design procedures. The ultimate strength behavior of platform tubular joints is highlighted by reviewing potential failure mechanisms and pointing out salient trends in available data. A brief review of the development is presented which extends the work of Washio (1) and Gibstein (2). Some comparisons are made between the new predictions and those of available methods. These give some indications of where conservatism may exist and show the range of parameters over which current practice may overestimate the lower bound to available experimental data. An example problem is included to illustrate how the new formulae can be used to design a typical K-joint. A final section discusses the needs for future research.
