Fastener schedule for Roof Rafter Bracing

[Supun93]

Hi. I need some guidance how to prepare a fastener schedule for additional bracings which we are going to install to a existing roof for strengthening. As you can see in this image, some of rafters has the diagonal bracing but some doesn't. I need to prepare a detail for the new diagonal bracings. Please advice me.Thank you.

I would analyze the rafters as a continuous member with a middle support at the brace location. Then just design the fasteners as a simple shear connection for the reaction.
