RELIABILITY ANALYSIS OF STAINLESS STEELCOVER PLATE JOINTS

Abstract

Stainless steel becomes more and more important inconstruction, particularly due to its highly ductility and strainhardening capacity. However, an experimental study on cover-plate joints conducted at the LaMI allowed evaluating somelimits of EN1993-1-4, considering complex failure modes. In thisstudy, a non-linear finite element model reproducing the complexbehaviour of cover plate joints is used to distinguish the majorparameters influencing the behaviour of these joints. A meta-model based on the quadratic response surface method is builtand exploited through a reliability approach in order to assessand enrich the available calculation methods for stainless steeljoints in the objective of reliability level of Eurocodes.
