Abstract

As large-span beams, plate girders can be excellent substitutes for rolled profiles that cannot be used in construction everywhere and at all times. Further, these members can withstand heavy loads that cannot be sustained by existing rolled profiles. Typical web plates are susceptible to buckling under loading. Cold rolling is an economical solution to prevent web plate buckling. Making deformations in the web plate enhances its geometric stiffness and strength around the weak axis. In this light, a detailed investigation of the capacity of plate girders with web deformations is in order. Accordingly, the Riks analysis was used to optimize the dimensions of these deformations and investigate their effects on elastic buckling in the plate and plate girder.
