Need Help with Pole Barn Loft Design

Is the rating for the Simpson hanger include a safety factor

I need to get one of those added to my plans!!

So after some more deliberation, I think I'm going with option 1: the 5 1/2" glulam beam supported by a Simpson HUCQ612-SDS heavy duty joist hanger.

The hanger is rated for a 5,315lb floor load. If my math is correct (which admittedly is a bit optimistic), that should be sufficient: each glulam beam supports approximately (6'+8')x12'=168sqft of loft. At 60psf loading (50psf live and 10psf dead), that's 168x60=10,080lbs on each beam. With a Simpson hanger at each end of the beam, each hanger must support 5,040lbs...which is less than the 5,315lbs its rated for. Plus, I'll likely add a separate brace beneath the Simpson hanger that's through-bolted to the post...just for good measure.

I've also included a more detailed floorplan of the loft.

Thoughts?

You may want to use the lower 3825# numbers for the brackets unless you are 100% sure about the lumber type -- what are the posts made of? Do they have any stamps/marks on them?
