Not that this will provide you with any guidance or understanding, but RISA makes RISABase, which will handle biaxial bending, and just about any other load combination you can dream up. We had it when I worked for a previous employer, and it was a nice piece of software, though it was complete overkill for 90% of the base plates we designed. It came in handy, though, when we had unusual loading or geometry. It uses a finite element model to determine stresses. After being somewhat neglected by RISA while they worked on their more significant software, I think it’s been updated to current codes.

Subject: base plate design
Hello,
Does anyone have an example or a good reference for biaxial base plate design? AISC Design Guide 1 deals only with uniaxial bending. Any references (books, manuals, papers, etc.), suggestions or ideas on how to design biaxially (interaction of some sort or design separately for both axes and then pick the worst case scenario) would be greatly appreciated.
Thank you,
JJ
