Curved girder bridges with corrugated steel webs have already been constructed around the world; however, few works have been done on their shear behavior. To investigate the shear behavior of corrugated steel webs in curved girders, a curved box girder with corrugated steel webs was investigated and tested in current study. The method of three-point loading was used in the test. Test results indicate that the girder failed due to nonlinear shear buckling of the webs and the shear yield stress of the material was less than the elastic shear buckling stress of the corrugated steel webs. Failure of the corrugated steel webs was initiated by the local shear buckling of one of the corrugation panels, which propagated to other panels. In the failure stage, the interactive shear buckling occurred in outboard and inboard corrugated steel webs. In addition, many cracks appeared in the concrete top flange nearby the top supports and the concrete bottom flange between the 1/4 span to 3/4 span. The girder with corrugated steel webs can continue to resist the load after the occurrence of shear buckling. For the design of this type of curved box girder, it is necessary to consider the shear buckling of the corrugated steel webs. |
