I'm a mechanical doing a preliminary analysis on a video display (17' x 17' x 3') to be located in a large auditorium (135' x 85'). The room has around 8 standard doors which make this an enclosed building. I am having trouble determining what lateral load i should consider on the display which is essentially a freestanding wall (aluminum framing bolted to the floor via expansion bolts. Would you consider this for internal wind pressure? Is there anywhere in ASCE 7 that gives a value for what pressure to use on freestanding walls? During a storm, the net pressure on the display should be zero (same on the front, back, and sides)...but during the change of pressure (increasing or decreasing) would there be any effect at ground level? Sort of like seats being ripped out of a plane when a door is ripped of. I have seen 5psf used before for internal walls but since this the display isn't part of the building envelope does internal wind load still apply?
