Addition of beam at deck edge

Not exactly. Load from any portion of the slab that is recognized as the "slab overhang" is applied to the adjacent perimeter beam, regardless of deck orientation. It's only within the limits of the framing that the program uses deck orientation for tributary load determination. That's why this topic comes up: Missing or incorrect loads on perimeter beams

Seth, thanks! But we are spanning the deck in the same direction/ orientation we are adding the beam. So the load should be distributed to the outer beams regardless in both the cases. Please let me know.

If it's one-way deck, hen adding a beam certainly changed the tributary area, the loads to the beam, etc. Check into these tech notes:
