Abstract: The noncompact web-slenderness limit in current design specifications is based on an assumed value of the plate buckling coefficient for a web subjected to flexure that is between the values for fixed and simply-supported ...

Abstract: The lateral torsional buckling (LTB) equations in some current standards are based on unified equations that are a fit to a large body of experimental test data. However, these curves tend to overestimate the capacities ...

Abstract: The I-section member lateral torsional buckling (LTB) resistance equations of the unified provisions underlying the current AISC and AASHTO specifications are a fit to a large body of experimental test data. It has been ...

Abstract: The current AASHTO specification requirements for the web bend-buckling strength-reduction factor (Rb) do not consider the influence of longitudinal stiffeners on the flexural resistance of steel I-girders subsequent to ...
