Improved Design Expressions for the Global Buckling Capacity and In-Plane Girder Stiffness of Torsionally Braced I-Girder Systems

Abstract

AbstractThe stability of girder systems is generally critical during erection and construction of steel bridges. Member stability is usually governed by the resistance to conventional lateral-torsional buckling (LTB), which is a function of the unbraced ...Practical ApplicationsStability bracing provisions have now been incorporated into new bridge design guidelines, offering bridge designers clear guidance on torsional brace system design. However, some inherent limitations exist in these provisions. For ...
