The slewing torque moment about the center of the tower is 477,940 ft-lbs.

Thanks for the responses guys. It makes sense that this wouldn't be a controlling limit state for the design assuming the foundation was embedded sufficiently. This being said, I still need to look at it. I assume the appropriate way to look at this would be to turn the torsional moment into a...

The torsion I am talking about is the slewing torque moment about the centerline of the tower.

I am working on a design for a spread footing foundation system for a Liebherr 630 EC-H 20 Litronic tower crane. I am wondering how to design for the torsion that would be expected from this type of crane. I have the value for the torsion created by the crane when in operation. Any tips or...
