Slip-resistant connections are always used when slip in a connection will endanger the serviceability or the slip resistance is used for ultimate limit reasons. Different guidelines/standards specify slip factors for common surface conditions. However, practice shows that in many cases the given slip factors are not comparable for the same surface condition. Furthermore, the available slip factors are valid for slip-resistant connections made of carbon steel. Currently there is no guideline/standard which prescribes a classification for slip-resistant connections made of stainless steel. Currently, different test procedures for the determination of slip factors exist. However, in several cases the test procedure is not clear in detail and allows several possible interpretations. In the frame of this study, the influence of different parameters on the slip-resistant behaviour of bolted connections was investigated. Furthermore, the relaxation behaviour of preloaded bolted connections made of stainless steel was also investigated. A comprehensive experimental investigation was conducted in order to provide a classification for slip-resistant connections made of stainless steel. In addition, an alternative method for preparing the faying surfaces of slip-resistant connections was developed in order to reduce the preparation time and cost on the one hand, and on the other to significantly improve the slip-resistant behaviour of the connections. A comparative study was then conducted to check the comparability of the results according to EN 1090 2, Annex G; and RCSC, Appendix A. Finally, a simplified test specimen geometry was developed based on the EN 1090 2, Annex G standard test specimen geometry in order to reduce the testing costs for the determination of slip factors.weiterlesen
