How to model weld between adjacent beams ?

      Hello community !nnI'm asking myself how to model the weld (or connection) between adjacent beams ?nMy problem : nI have a storage rack (gaz bottles or others) and each cell is modelled with beam 1d element, and each cells is welded to adjacent one in both x-y directions.nBut I cannot find the correct way to model the connections between the cells.nWith 2d shell there is no problem, but i would like using only 1d elements.nnThanks a lot for your help !n

      ,nCould you share an image of your model and tell what the objective is? The general practice is to use shell elements to model welds. You could model the rack using 1D elements but the weld stiffness (and other related effects) won't be considered. This is preferable in cases where the weld effects are not significant and the overall structure deformations/stresses are needed. You could always add beams in between to connect 2 beams (I don't see the point of using a connection). You could check this tutorial series
      describing a 1D analysis of a space frame.nRegards,nIshan.n
