slick- what is that document? Nice to know I've been thinking about it right all of these years. I have always thought of hangars, garages, and any other three-walled structures as the worse when it comes to wind. Like a paper grocery bag laid flat, the air can enter in but has a hard time leaving, thus causing the large internal pressures.
This has been confirmed forensically after damaging wind events where garage doors were blow inwards and then windows, doors, or worse case, walls/roofs are then blown outward. Though that document did not spell it out, it should also be clear the left-right wind direction will produce your worse case uplift on the roof due to the large internal pressure and upward pressure on the ceiling (if its there) or on the underside of the roof....
In Florida this has led to better garage doors, better tracks, and even stiffener posts and beams that can be quickly installed prior to a hurricane.
