Bending behaviour of corrugated webs
In order to verify if the web can contribute to the bending capacity of
the whole girder, the failure moment is compared with the bending
moment corresponding to the yielding of the flanges. It was found
that the web contribution could be neglected.
M f ≃ M y,f M y,w ≃ 0
y,f
The bending capacity of the whole girder is affected by many
parameters. The following factors were analyzed:
a. ratio between the flange and web thickness;
b. ratio between the flange and web yield stresses;
c. corrugation configurations.
The stresses in the web due to bending are equal to zero except for
small regions very close to the flanges where the web is restrained.
