Load combination factors for multiple overhead cranes

[Stockton2008]

In the case of multiple overhead cranes and runway beams installed in one single factory building, what are the load combination factors of cranes for ultimate and service structural calculation in steel or concrete frame design, based on MHI, MBMA, or AISE? Thank you.

I believe you would want to use AIST Technical Report 13. It has separate load cases for multiple cranes loaded together and single cranes.

Though it depends on where your project is and what type of building it is.

AISC Design Guide 7 is a good reference also.
