I posted here because I was having a lot of difficulty finding any AASHTO LFD-specific design examples, and the ones I...

    AASHTO Std Specs (LFD): axial compression with (flexural-)torsional buckling?

    Appreciate the input guys! I am quite familiar with the MBE and I've been consulting it throughout this process, yes. Re: curvature, it's a bit of an unconventional situation: three of the four spans have all-straight girders... except for the right exterior girder, which is curved. And then the...

    AASHTO Std Specs (LFD): axial compression with (flexural-)torsional buckling?

    Hey guys, I'm currently working on a bridge load rating using Standard Specs (17th Ed.) LFD methodology. Need to provide axial-force rating factors for steel cross-frames and lateral bracing members, most of which are either T or single-angle sections. But Std. Specs don't really offer much...
