Development of Partial Environmental Load Factor for Design of Tubular Joints of Offshore Jacket Platforms in Malaysia

The reliability analysis methods have been effectively applied to develop load and resistance factor design (LRFD) codes, such as the ISO 19902, that provide optimum structural safety taking into account the uncertainties of both the load and resistance parameters. Although, these methods have bee...
