| Abstract: |
The stress concentration factors of tubular joints have taken great attention among engineers. The DNV/GL-RP-0005 is covering this topic quite well for simple and clear joint cases. For complex joint and geometry, where joint classification isn’t available and limitation on validity range of non- dimensional geometric parameters, the challenges become a fact among engineers. The classification of joint is important for the fatigue analysis. These joint configurations are identified by the connectivity and the load distribution of tubular joints. To overcome these problems to some extent, this paper compares the SCFs which were obtained by parametric equations given in DNV/GL-RP-0005, finite element analysis and full scale experimental test results of four different types of tubular joints in offshore jackets. Finally, the validity and limitation of each method are discussed. |
