Help decipher gable wall details for new build

[cliffcharb]

So as I wait for an answer from the draftsmen/engineer that drew up my plans. I'm looking for thoughts from others concerning the required straps as I like to understand the purpose of everything. As a note I am in a 150mph wind zone.
Per the plans the gable ends sheathing must be spilt between the gable & wall. Makes sense so there is no "hinge" at the top plate.
My issue is the 24" straps shown @ each stud on the exterior of the sheathing. What exactly would those accomplish? Wall studs are 16", while gable verticals are 24" so every other strap would just be attached to the sheathing.
Unfortunately our city inspectors are pretty much worthless, as the few questions I've asked during this build were always directed back to my plans or engineer.

Probably he easiest to make your studs line up on that end. It wont matter structurally, as the load is taken by the truss, and 24" oc is a legit framing as well.

The straps are to tie everything together so it acts as one resisting force. In other words it helps to hold the roof structure to the walls which are attached to the foundation.

We are in a 140mph wind zone, seeing that detail reminds me of how happy I am to not build houses anymore!

You could order the trusses with studs where you need them - to line up with the wall studs. Probably a very minimal up-charge for this.
The drawing appears to show 2X studs in the gable turned flat. You can add lots of stiffness upstairs by nailing another stud to the side of the truss studs. Add plenty of diagonal bracing to the gable ends. That is probably already in your plans given your wind ratings.

Shouldn't the straps be nailed through the sheathing and into the bottom chord of the truss (also webs of the truss if they line up)?

Only answer I received is that they prevent a hinge point at truss and top plate. Which i assumed. Yet the wall studs and vertical chords only line up every 3rd wall stud.

Sounds like you already have a wall framed and gable end truss installed on top. Whoever designed this should have thought this through at the design stage.

Now you can fix it by adding studs where you need them. That should not be a complicated job.
