Abstract
Slip of slip-resistant connections has to be prevented either for serviceability or ultimate limit state reasons. EN 1090-2 specifies slip factors for often used surface conditions. For deviating conditions, slip factors have to be determined experimentally according to Annex G of EN 1090-2. The practice shows, that the slip test procedure according to Annex G is not clear in detail. For instance, the slip load has been defined as the load corresponding to a slip of 0.15 mm. Furthermore, static tests have to be performed using a “normal speed” which is not clearly specified. For these and other reasons, a comprehensive investigation is going on to be carried out to resolve these problems. First results are presented in this contribution.
