ULTIMATE COMPRESSIVE STRENGTH OF ORTHOGONALLY STIFFENED STEEL PLATES

The authors present an approximate method to estimate ultimate strength of orthogonally stiffened steel plates subjected to uniaxial compression. The method is based on the orthotropic plate theory and can treat all collapse modes that occur on the orthogonally stiffened plates; for example, overall buckling of the main plate together with longitudinal and transverse stiffeners, and overall buckling of the main plate between the adjacent transverse stiffeners together with longitudinal stiffeners. In addition, the method includes the effect of the local buckling that occurs on the longitudinal stiffeners and/or the plate panels bounded by both the longitudinal and transverse stiffeners. Thus, the method is practical for the design of actual steel stiffened plates; for example, those subjected to eccentric compression, nonuniformly stiffened, or having large stringers together with longitudinal stiffeners. Many test results of longitudinally and orthogonally stiffened steel plates subjected to uniaxial compression are compiled to compare with the ultimate strength predicted by the present method. Comparisons reveal that the present method shows good agreement with test results.
