Well, there are may FEM system that can do such calculations, and every user will have different preferences in selecting one. As a quick example I have simulated a steel slab under dead weight with Tochnog. All details are under this link: http://www.l5.pk.edu.pl/~putanowr/dokuwiki/doku.php?id=en:gallery:slab This is not the geometry you have described but with little scripting in any language it is easy to convert gmsh generated grid to Tochnog format. Visualisation was done with ParaView but I am sure you can achieve the same with gmsh.
