I need to anlalyze the structure consisting of 12 in diamater pipes and 1" steel plates welded altogether.Pipes form a "spoked" structure about 27 ft in diamater reinforced by 1" steel plates in between. I have used shell and solid elements before in ProMechanica but never beams.I want to use shells but I am afraid shells are not appropriate elements for structure-type models.Any thoughts? Thanks.
