Structural durability assessment of welded offshore K-nodes by different local design concepts 

Journal Title: Frattura ed Integrità Strutturale - Year 2009, Vol 3, Issue 9

Abstract

The structural durability design of complex welded structures should not rely only on one single design method but should apply different methods for assuring the reliability of the assessment. In this context the application of the structural stress concept, notch stress concept and crack propagation concept are discussed through the example of K-nodes used in energetic offshore constructions like oil platforms or wind power plants, presenting the state of the art.
