Stability behaviour of stiffened curved plates subjected to pure compression
https://orcid.org/0000-0003-3153-8594
Abstract This paper investigates the stability behaviour and load carrying capacity of longitudinally stiffened, transversally curved steel plates under compressive stresses. The behaviour of stiffened, curved plates is a complex problem, especially due to the interaction of curvature, relative stiffness of the stiffeners and initial imperfections. A comprehensive parametric study is presented to investigate the effects of curvature, plate slenderness, size and shape of stiffeners on the ultimate resistance of stiffened curved plates. The aim of the study is to explain the behaviour of such structures and to demonstrate the benefits that can be obtained from bridge decks with curved plates. From the results some important conclusions are drawn regarding the structural behaviour and the positive effects of curvature on the cross-sectional resistance. A study on the influence of geometric imperfections on the load-bearing capacity is presented, which is based on the modification of nodal coordinates by means of sine-shape functions.
Highlights EN 1993-1-5 strongly underestimates the resistance of stiffened, curved plates. Design guidelines for the ultimate resistance of stiffened, curved plates under compression. A general form of the buckling coefficient is derived for orthotropic shell buckling. The new method is compared with numerical results and a good correlation is achieved.
