The behavior of stiffened plates with high strength steels (SM570 and POSTEN80) are experimentally investigated The results of compression tests on 7 specimens are reported herein. Based on the results the effects of width-thickness ratio of plate element and flexural rigidity of rib are examined. The strength behavior of stiffened plates are discussed with the comparisons of ultimate strength and design strength curve Furthermore experimental and FEM analysis results are also compared.
