Abstract: Longitudinal stiffeners are often attached to increase the buckling strength of thin-walled box girder flanges. The minimum required rigidity for longitudinal stiffeners for curved box girder flanges is given by the AASHTO ...

Abstract: This paper presents an optimum design of longitudinal stiffeners for box-girder compression flanges. The buckling behavior of longitudinally stiffened compression flanges has drawn considerable interest from early pioneers ...
