Study on the Effect of Corrugated Webs in Steel I-Girder Bridge

The corrugated steel webs are used to allow without continuous stiffeners for the steel and composite bridges. This structure has many advantages compared to steel girder with flat web. A corrugated web steel bridge, corrugated steel webs increase the stability of the girder web, increase the torsional stiffness and reduce the weight of the steel girder. It is many beneficial qualities, such as lower dead-load, increased shear buckling strength and so on. In this article, the advantages and applicability of corrugated steel ribs are presented. The comparison between the behaviors of flat steel I-girder and corrugated web steel I-girder is performed to clearly see the effect of the corrugated webs.
