BASED ON 16d COMMON WIRE NAILS (0.162 "x3 -1/2 ") OR 16d THREADED HARDENED -STEEL NAILS (0.148 "x3 -1/2 ") <br /> WITH A MINIMUM PENETRATION OF 2" INTO SIDE GRAIN OF MAIN MEMBER. <br /> 2. NAILS SHALL BE PROVIDED IN PAIRS AT A MAXIMUM SPACING AS SHOWN IN TABLE WITH A <br /> MINIMUM OF THREE (3) PAIRS OF NAILS PER JAMB. NAILS AT TOP AND BOTTOM <br /> OF JAMB SHALL BE PLACED A MAXIMUM OF 6" FROM THE END OF THE JAMB. <br /> 3. LOAD PER JAMB CALCULATED BY TAKING DESIGN LOAD (PSF) TIMES DOOR WIDTH (FT) DIVIDED BY 2. <br /> EXAMPLE: DESIGN LOAD = 30psf <br /> DOOR WIDTH = 16ft <br /> LOAD PER JAMB = 30psf x 16ft/2 = 240Ib /ft <br /> 4. CHART IS BASED ON 6-6" MINIMUM AND 24' -0" MAXIMUM DOOR HEIGHT. <br /> 5. DOOR JAMB TO BE 2x6 NO. 2 GRADE SPF LUMBER OR BETTER MOUNTED DIRECTLY TO SUPPORT STRUCTURE. <br /> 6. DESIGN OF THE SUPPORT STRUCTURE SHALL BE THE SOLE RESPONSIBILITY OF THE BUILDING DESIGNER <br /> AND SHALL BE DESIGNED FOR THE JAMB LOAD LISTED IN ABOVE TABLE AS CALCULATED PER NOTE 3. <br /> 7. EDGE DISTANCES, END DISTANCES AND SPACINGS SHALL BE SUFFICIENT TO PREVENT SPLITTING OF THE WOOD. <br /> 8. CALCULATIONS CONFORM TO ANSI /AF &PA NDS -2005. <br /> Approved <br /> Mark R.
