Composite Deck STADD Pro v8i

[Cherokeedesign]

I thank Sye123 for answering my previous question.
New related Questions. Are Composite Deck concrete slab considered a continious "rigid" member that causes all nodes in slab to move together? Or must these nodes in the Composite Deck be "locked" together using the Master Slave command to get this "rigid" condition?
To use Composite Decks, the floor of a building must be broken up into rectangular parts and given a name. The width of the concrete slab attached to each steel beam is given a width to compute the composite beam properties. Does this prevent the slab to act as a continious unit as happens in a real composite decK slab?

Thanks for your reply,
