Abstract
Corrugated webs are increasingly used in many civil engineering applications especially in the girders of bridges. They offer increased out of plane stiffness and higher shear buckling capacities. The geometry of the corrugations alters the shear stress distribution in the webs when compared to flat webs. There are mainly two shear bucklings modes. Local buckling involves a single fold whereas global buckling involves many folds and extends over the entire depth of the web. Local buckling is calculated from classical plate buckling equations whereas global buckling is computed by treating corrugations as a flat orthotropic web. Recently a new method known as Direct Strength method (DSM) has also been applied to determine the shear capacity of beams with corrugated webs. In this paper various shear resistance models of girders with trapezoidal webs proposed by Lindner, Johnson and Cafolla, EN1993-1-5 and DSM are compared with experimental data to determine their efficiencies and applicability for design purposes.
