Stability behaviour of stiffened curved plates subjected to pure compression

This paper investigates the stability behaviour and load carrying capacity of longitudinally stiffened, transversally curved steel plates under compressive stresses. The is a complex problem, especially due to interaction curvature, relative stiffness stiffeners initial imperfections. A comprehensive parametric study presented investigate effects plate slenderness, size shape on ultimate resistance stiffened plates. aim explain such structures demonstrate benefits that can be obtained from bridge decks with From results some important conclusions are drawn regarding structural positive curvature cross-sectional resistance. influence geometric imperfections load-bearing presented, which based modification nodal coordinates by means sine-shape functions.
