Info on verticle load rating of 1/2 in OSB plywood with 2by2 frame?

Info on verticle load rating of 1/2 in OSB plywood with 2by2 frame?

(OP)
I'm with an amusement park that's hosting a haunted house in a tent this year.  We need to prove to the fire marshal that our structure is strong enough to support our sprinkler system that is proposed to be bracketed and supported on the top of the maze structure.  
The structure is made from 4 by 8 panels aprox. 1/2in OSB plywood with a 2by2 box beam frame around its edge screwed on with 1 5/8 in drywall screws.
Panels stand vertically (4ft down) and are connected on their sides (8ft side) to other panels via a-21 metal brackets.  
The panels are arranged in a 0 deg, 30 deg, and 60 deg configuration to provide a walkway or maze through this event. (something like this /\_/\__/ ).  There are around 300 panels.  
The top of the panels are then braced with a cris-cross structure of 1 by 2's that are then screwed into the top of each wall.
The sprinkler system weighs approximately 900 lbs total with the water.
Can anyone provide information that will prove that the vertical load rating for our panels is great enough to support the load of the sprinkler system?

You must be checking this with some code specifications, and there should be a way of checking the as built panels. If the reclaimed standing code does not address this thing, and no indication on what substitute code you should employ is made, you are left to the science of construction. Then you would have to make your own assumptions on how your structure works, nails, ribs and all, and analyze for the projected configuration for the code (or whatever suitable) loads and load combinations.
