... on the static strength of tubular joints (Wardenier et al. 1991, Packer et al. 1992). Extensive research on tubular joints has been carried out all over the world in the last 16 years and some of those developments have been incorporated in CIDECT Design Guide 9 (Kurobane et al. 2004). There is a need to update...

INTRODUCTION In two of the tests of Yonemura et al (1996), it was reported that there was insufficient melting of the weld metal, and therefore it was doubted whether...

INTRODUCTION Existing design formulae, such as AWS, API, CIDECT and AIJ Codes, are either too complicated or inaccurately estimate the ultimate strength for new other joints. To make simpler design equations...
