This event marked the launch of a new, alternative transition piece/monopile (TP/MP) connection for the offshore wind market. An extensive qualification programme in terms of numerical modelling and testing was set up prior to installing the slip joint. This process was witnessed, reviewed and accepted by DNVGL. It led to a certified slip joint design for Borssele V, with a 9.5 MW wind turbine generator (WTG) on top of the foundation as well as an A‐level component certificate for the slip joint in general. The installation of the slip joint for Borssele V was the first use of this connection in a commercial full‐size wind turbine.","PeriodicalId":54183,"journal":{"name":"Steel Construction-Design and Research","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46627925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research on ultimate capacity of bolted joints under combined tension and shear actions, twin shear actions, and combined tension‐twin shear actions is relatively limited. The aim of this paper is to calibrate the fracture locus of grade 10.9 bolts using the mesoscale critical equivalent plastic strain (MCEPS). We use ductile fracture simulation to numerically evaluate the ultimate resistance of bolts subject to multiaxial loading and compare the results with the current design standards. The results show that predictions for grade 10.9 bolts subject to multiaxial loading in Chinese code GB 50017 and American code AISC‐360 are not on the safe side, while predictions in European code EN1993‐1‐8:2005 are slightly on the conservative side. We propose two modification factors to improve prediction of bolt strength subject to multiaxial loading; namely the multiaxial loading factor for shear resistance ξv and the multiaxial loading factor for tensile resistance ξt.","PeriodicalId":54183,"journal":{"name":"Steel Construction-Design and Research","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42585255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the component resistance is determined by manufacturing-related imperfections. Due to a lack of knowledge and the absence of easily applicable design approaches, the use of cast steel components is usually rejected or countered by the highest demands on manufacturing quality. This blanket choice is usually uneconomical and not necessary from a technical point of view, since even major casting defects do not necessarily reduce the performance of a component. In this paper, an easy-to-use design approach is presented, which allows the determination of manufacturing quality based on local stresses. The link between fatigue strength and allowable defect sizes is established by newly defined resistance categories. The component design is carried out by limiting maximum stress ranges, is based on established verification concepts, and is thus directly adapted to practical construction applications. Influences such as medium-voltage dependence, shape tolerances, brittle fractures, stress gradients and interaction of neighbouring flaws are considered by reduction factors or additional conditions.","PeriodicalId":54183,"journal":{"name":"Steel Construction-Design and Research","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46283676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
