Just looking for some input on the attached roof framing sketch/concept. I'm a little unsure about how to resist uplift with these 2x8 purlins on edge bearing on top a glulam beam. Roof pitch is 2.5:12. The blocking between the purlins is held in place with framing angles. The purlin space will be insulated, with a gyp board ceiling. Typically these purlins are secured to the sides of the rafter beam with face-mount hangers, but this setup is different. I think I can satisfy the uplift forces with the truss screws angled up from the bottom thru the top ply of the glulam into the purlin. Any additional input or suggestions is appreciated.
