Abstract:

In accordance with Louisiana Department of Transportation and Development (DOTD) policies and guidelines for bridge rating and evaluation, all bridges shall be rated using the Load and Resistance Factor Rating (LRFR) method as specified by the American Association of State Highway and Transportation Officials (AASHTO). Both local buckling and lateral torsional buckling (LTB) are considered when determining flexural resistance of a girder compression flange. LTB resistance is determined for uniform major-axis bending moment, and a moment gradient factor (Cb) is applied to account for the effects of variable moment along an unbraced girder length.
