Steel Girder Stability during Bridge Erection: AASHTO LRFD Check on L/b Ratios

Abstract

The erection of steel plate girders during the construction process of a steel bridge is a complex operation, which is often left to the contractor and/or the subcontractor to plan and execute. Rules of thumb have been developed through experience to check the lateral torsional buckling of the steel girder during erection using the maximum
