No members loaded for a floor load generated

I am modeling a digester tank , there is a walk above the dome resting on rcc wall, to transfer the slab dead load and live load i have created dummy elements over the walls and applied the dead load and live load as floor loads by grouping the beams, the staad in the modeling mode it shows the load distribution of floor load but when I run the model the warring shows up saying , NO MEMBERS LOADED FOR A FLOOR LOAD GENERATED 

Can i ignore the warning or is there some other way to transfer the dead load and live load to the walls without modeling the slab itself
