Okay so I’ve been researching some options for ridge beam straps/brackets and hurricane ties for rafters (to place into a drawing detail) and I found a few helpful dwg files on simpsons website. My question is, in my search for rafter to ridge and rafter to plate fasteners it looks like everything is detailed using I-joists in the place of rafters. Is this the standard now? I’m a little lost with this, they’re called I-joists for a reason I assumed. Why does every detail simpson has involving rafters have an I-joist in place of rafters?

Editorial choices for the Simpson website may get a better response by contacting them.
The products shown in drawings which feature I joists are designed to work with them.
The engineering has to be different (hole locactions....fastener use....) than products intended only for use with solid lumber.

This page shows details for solid sawn lumber and for trusses. Not just I-joists.
Hey thanks, but a link may not be showing in your comment
It is not uncommon for rafters to be built from solid lumber, from I joists, or to frame roof supports using engineered roof trusses of various designs.
As you may have guessed, they are called I joists because in cross section they resemble a capital I (in fonts which include a horizontal line top and bottom, anyway....)
Similar to nomenclature of steel I beams.
Forgive me, what i meant was - I assume they're called I-joists for a reason - and not "I-Rafters" lol.
These particular brackets and straps were created because the use of I-joists as rafters predicated the need for them.
Solid lumber, historically, has had other options for fastening.
Thanks everyone, i guess what I'm having trouble finding is reference material, for standard stick framing. which is literally the only method i have ever seen f/ residential.
So as you could imagine, digging for reference material and EVERYTHING i see is NOT stick framing, i figured the best place could be simpson with their wide range. But everything is engineered materials (trusses, I-joists, etc).
