Results of elasto-plastic finite element analysis are presented for panels having boundary conditions appropriate to full-depth web panels, for square, long and tall panels with side ratios ranging from 1 to 5 and with b/t ratios 80, 120, 180. Convergence studies are described, and it is noted that shear panels require a finer mesh than compression panels. Stress-strain curves are given for all solutions: whereas the ductility varies, maximum resistance occurs at a strain approximating to the shear yield strain. Principal stresses are compared with alternative tension field models, which differ more from each other than they do from the computed tension fields. Unlike the models, extensive yielded zones do not develop until after maximum
resistance has been reached.
