1 Proposed Modification to AASHTO Cross-Frame Analysis and Design Cross-frames are important structural components that serve many functions throughout the service life of steel I-girder bridges. They primarily act as stability braces to enhance the lateral-torsional buckling resistance of the bridge girders during erection and deck construction.
