Question

RAM structural system - slab cantilevers

I have a project with large slab cantilevers (3ft). Does RAM take into account the extra moment associated with the loads on these slab cantilevers?

See image.

For example for the facade line load, does it take into account that the reaction force from the facade is located 3ft away from the beam cantilever tip, and thus results in an extra cantilever moment M=f x 3?

Or does it just puts the reaction force on the beam cantilever tip and ignores the extra moment?

Thank you.

If it's one-way deck, then the overhang load is all translated to the edge beam without amplification. 

I thought this was for Ram Structural System. It looks like one-way steel deck to me.  

Hi Seth, by one-way deck do you specifically mean the mesh property of the cantilever or the design strip? if the cantilever is modeled as two-way (mesh property) and oneway design strip, does RAM cater for the forces along the strip perpendicular to the cantilever as torsion? tried to iterate with sketch below:

Many thanks

Apologies for not illustrating concrete thicknesses on the sketch. please see below screenshot of ram model:
