This is not the way I would want to try to solve the issue but here's a stab.
Figuring the uplift is a trig problem but it's late and my brain says do it the graphical way, by looking at the proportions of the triangle formed. The sides of which are; the top of the joist, the vertical distance of the beam above the joist, and the hypotenuese of the triangle is formed by the strap. For example, if the tension force being resisted was 1000 lbs, the beam were 2" above the top of the CJ and the strap was connected 12" from the beam the uplift force would be 2/12 of 1000 lbs, 167 lbs. By that method I'm coming up with 1014 lbs in the strap and its' connection. the numbers are not for this situation, just an example.
