We have a project where there is a very high corridor at a high school (45-50 feet high). There are 30-inch deep steel 'I' beams spaced at around 20-ft apart.
Should this be considered obstructed or unobstructed?
Should deflectors be at 1"-12" below deck, or can they be lowered to maximum of 22" below deck? Do all deflectors need to be at the same elevation?
Since the beams are deeper than the deflector elevation, I'm looking at Table 188.8.131.52.2 for distances from the beam to avoid the beam with the sprinkler spray.
Thank you in advance for your input.
