Buckling of stiffened steel plates---a parametric study. G.Y. Grondin, A.E. Elwi and J.J.R. Cheng. J. Construct. Steel Res., May 1999, 50(2), 151--175.
A finite element model was used to investigate the stability of plates stiffened with two-shape stiffeners. Four series of stiffened plate panels were modelled using a finite strain four-mode shell element. The model was validated using the results of tests on full-size stiffened plate specimens and was subsequently used to perform the study of various parameters, details of which are presented. The results, which were compared with API and DnV design guidelines indicate that the guidelines are generally conservative for cases where initial imperfection magnitudes do not exceed the guidelines' prescribed maximum. 18 refs.
