Bearing length question on a beam

I know per code, that the bearing length for a steel or wood beam is 1.5". But was wondering of a way to increase. Been googling, but haven't really found anything that addresses it.

Scenario:

Two 1.75" LVL beams sistered together to give 3.5" bearing length. Will be running floor joists on top of these beams. Instead of lapping the floor joists over the beam, thinking about butting them so that I have a straight line for the joists. My assumption is the bearing length should be sufficient, but would like more. Thought of nailing a 2x6 along the top of each side of the beam to add another 1.5" of bearing for each joist. Does that count as adding bearing length?

Not sure what code edition GA follows but WI states: Wood floor joists with ends that intersect over a beam shall have the ends overlap at least 3 inches and be securely fastened together with at least two 12d common nails or the ends shall be ****-jointed or face-jointed and fastened with ties, straps, plates or solid blocking.

You could raise your LVL's to top of joist and hang them off of it. Of course, if you're using engineered joists just make them full length.

I think it is the same here.

Too late for that, lol. I already have the beams in place. As fas as using full length, they total span is 60 ft. I have beams at 15ft, 30 ft, and 45ft so that the floor joist spans are 15ft.

The 2"x 6" along each side of the beam will count, IMHO. In many older buildings in my neck of the woods a 2x ledger board was frequently used to support joists framed into a beam. Obviously the bearing length was only 1.5". Your local building inspector will have the final say. Check with him or her.

Thanks everyone for the responses. I just went with lapping, and had them start half way over a wall stud so that by the other end, they will be halfway over a wall stud, just on the other side. At least it will be covered by plywood so it won't bother me as bad for the rest of my life...lol
