Abstract

Behaviour of structure can be measured by probability of failure or reliability index. Target reliability of components is found as per API RP2A WSD. Load factors are developed in such a way that the reliability index of Jacket is at predefined target level. The reliability indices of ISO LRFD design for a range of load factors are determined. When ISO load factors are plotted against the corresponding API target reliabilities, the intersection point gave the proposed load factor. Not only the Jacket reliability designed as per new load factors will be higher than the target, but also it will ensure safer Jacket.
