Load combination factors for multiple overhead cranes 1

[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.

Thank you very much. Where can I get e-version copy of AISC Design Guide 7?

AISC DG 7 is free if you are a member of AISC.

I am seeing a word document version of AIST technical report 13 below. Not sure how up to date this is or what type of version it is. It is weird seeing this as a free download as a word document from their website.

AIST 13 is for mill buildings and might be a bit heavy for a factory, but it is a good upper limit
