Permanent Bracing Design for Trusses

[Seversen]

I am looking for a resource that covers permanent bracing of truss systems due to wind/seismic loading. I have read through the tech notes from Light Gauge Steel Engineers Association but they seem to only cover bracing for the forces in the truss members. Any assistance in this matter would be appreciated.

Thr bracing of the truss system is to provide web stability.

Drag loads are due to lateral (horizontal) loads generated in high-wind or seismic events. These loads are generated within the structure and transferred into load carrying elements (like drag strut trusses, shear walls or roof diaphragms) which then transfer the loads to the foundation and then safely into the ground.
