PURLIN FASTENER DESIGN CALCULATIONS:
DESIGN FASTENER: #8 x 3"DECK SCREW THROUGH SHEATHING INTO SYP TRUSS/RAFTER.
ALLOWABLE PULL-OUT CAPACITY= 141 POUNDS/SCREW (INCORPORATES MINIMUM SF=5).
USE 2 SCREWS AT EACH FASTENING POINT (EACH TRUSS/RAFTER).
USE MAXIMUM WIND PRESSURE =53.2 PSF
MAXIMUM PURLIN SPACING = (141)(2)/(2)(53.2)=2.65' = 32"
DESIGN: 2X4 SPF PURLIN AT 28" ON CENTERS FASTENED THROUGH SHEATHING TO EACH
TRUSS/RAFTER WITH TW6(2)#8 x 3" DECK SCREWS.
ROOF PANEL FASTENER DESIGN CALCULATIONS:
DESIGN FASTENER: #10 SCREWS INTO 2X4 SPF PURLIN
ALLOWABLE PULL-OUT CAPACITY= 168 POUNDS/SCREW (INCORPORATES MINIMUM SF=3)
PURLIN SPACING=28 INCHES ON CENTERS.
USE 1 SCREW AT EACH FASTENING POINT ALONG EACH PURLIN.
USE MAXIMUM WIND PRESSURE = 53.2 PSF
MAXIMUM FASTENING POINT SPACING = (168)/(2.33)(53.2) = 1.36'= 16"
DESIGN: USE ONE(1)SCREW @ 15.75"O.C.(ON NAILING STRIP EACH PANEL)ALONG EACH PURLIN.
