METALLIC PRODUCTS CONTINUOUS VENTILATORDESIGN EVALUATION AND CERTIFICATION
This is to certify that the construction of the Metallic Products 10ft. sections of ridge ventilators with 10ga. Base Straps, 24 ga. Baffles, and 26 ga. Sides, Ends, Skirts and Dampers will withstand wind loadsof 100 MPH when adequately supported by the roof panel to which it is attached. Minimum requiredattachment is No. 14 self tapping screw to the top of each major roof panel rib.
Wind load is determined in accordance with the MBMA Design Manual procedure. The following analysis
could be construed as Parts and Portions of the building structure, such as load supporting systems ofstructural roof panels, purlins, bracing, and framing.
The typical installation procedure for vents is to fasten each side skirt to the roof panel with a minimumof 1-#14 STS @ 12" o.c. (2 fasteners per linear foot of vent). Various Manufacturers test data has indicatedthat the resistance of these fasteners exceeds the design values used by Metallic Products by a factorin excess of 2 1/2 to 1. This design value is 50 lbs. pull out and 100 lbs. shear per fastener when installedin 26 ga. galvanized panels of 50,000 psi minimum yield stress.
The probable extreme standard condition would be a roof with mean height of 60 ft. and a slope between10 and 30 degrees (4/12 included).
1. Assume the clear distance at the ventilator between roof sheets to be 24" max. (This is probablygreater than would occur for a 12" throat vent.)
2. Assume total vent is in Z edge strip. Building would have to be at least 100 ft.wide and 25 ft.high at the eave.
3. Velocity Pressure q = 30.4 PSF (100 MPH) (Table 5.2b in the MBMA Low Rise Building SystemsManual)

METALLIC PRODUCTS CONTINUOUS VENTILATORDESIGN EVALUATION AND CERTIFICATION
12" Standard Throat Ventilator: The 24 inch ridge opening results in 2 x 47.88 = 95.76 lbs. per ft. uplift onventilator or 47.88 lbs per fastener which is less than the 50 lbs. per fastener design stress. The ventilatoris less than 2 ft. high resulting in a shear stress of less than 50 lbs./fastener from an equal horizontal windload.
The building design used to create this wind loading exceeds the dimensional parameters of moststandard buildings offered by Metal Building Manufacturers. The location of the vent at the very end of
the building ridge (within the Z edge strip) is not unusual when continuous vents are used for the fullbuilding length. However, a more common arrangement is to place the vents, one in the center of eachbay or to begin the continous run, one ventilator back from the end wall peak.
