15 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.

stresses. Conventionally the contribution of the web to the ultimate<br />
bending capacity of a beam with corrugated web is assumed<br />
negligible, and the ultimate bending capacity is calculated using the<br />
plastic modulus of the flanges.<br />

if the web can contribute to the bending capacity of the whole girder.<br />
