Since suffering hurricane damage, my house and many many more in Florida now have the modern version of "Purlins. Commonly called "Rat runs.' Mine has 4 sets of them besides many angled reinforcing braces. The rat runs are pieces of 2X4 nailed between each truss. These 22.5" pieces run in a straight line from one gable end to the other. Then attached to them are the actual rat runs, long 2X4's butted end to end from gable to gable. So now a wind load on one gable, besides being cross braced and angle braced is braced by each and every truss member.. The amount of wood in my attic is now likely double what it was when the house was built.
Old ideas become new again.
