Experimental and Numerical Studies on the M-V-N Interaction of Longitudinally Stiffened I-girders

In this paper we study the bending and shear interaction of compressed and longitudinally stiffened I-girders. Therefore, two full-scale tests were designed, and results are discussed. Moreover, to fill the gap in knowledge about imperfections in longitudinally stiffened girders, detailed information is given on initial geometric imperfections due to welding for the girder panels tested. Additionally, a finite element model is presented and verified against the experimental results. Following those outcomes, the resistance is compared against the effective width method and conclusions are drawn. These first results suggest the need for further investigation by numerical parametric analysis to analyze an improved design approach for the new version of the M-V-N interaction.
