With these light loads and at least a 2x8 joist you can as an alternate back nail with 16d common nails from the first ply of the girder to the end of the joist. The allowable capacity is (4)(108)(2/3) = 288#. The highest nail should be 2" or more below the top of the joist, and the lowest nail at least 2" from the bottom of the girder, and 1" from the bottom of the joist. The remaining should be between and no closer than 1" apart.

This is a more difficult connection since you have to hold up the joist while you nail into it.
