... taken into account. Due to the lack of normative design rules, the use of high-strength steels and blind rivets results in open questions for the structural engineer regarding the load-bearing behaviour of the connection and its fatigue resistance. The authors address these questions and give...

... of offshore wind energy converters. According to the current standards, the choice of the steel grade does not have an influence on the fatigue resistance. Now, the wall thickness can be reduced by the use of high strength steel. This has to be taken into account also with regard to different methods of post...

... ABSTRACT The fatigue resistance of longitudinal attachments is influenced by the length and the geometrical form of the attachment on the one hand and the quality and the execution of the weld on the other hand. Now, to estimate the influence of such attachments on the fatigue strength...

... ABSTRACT Enhancement of fatigue resistance performance of welded joints by UIT is being evaluated in full-scale steel rolled beam specimens having yield strength of 50 to 60 ksi (345 to 415 Mpa). W27×129 rolled beam sections having cover plates with three different end weld details...

... A reliable prediction of the fatigue resistance of steel structures may be best achieved by testing large scale test specimen that represent the actual conditions of fabrication and loading as far as possible. Due to the expenses of such tests, numerical methods are needed that allow to estimate...
