4) Roof design snow load has been reduced to account for slope.
5) This truss has been designed for greater of min roof live load of 12.0 psf or 1.00 times flat roof load of 16.8 psf on overhangs
non-concurrent with other live loads.6) This truss has been designed for a 10.0 psf bottom chord live load nonconcurrent with any other live loads.7) * This truss has been designed for a live load of 20.0psf on the bottom chord in all areas where a rectangle 3-6-0 tall by 2-0-0 wide will fitbetween the bottom chord and any other members.
8) Provide mechanical connection (by others) of truss to bearing plate capable of withstanding 167 lb uplift at joint N and 167 lb uplift at joint
H.
9) This truss is designed in accordance with the 2018 International Residential Code sections R502.11.1 and R802.10.2 and referencedstandard ANSI/TPI 1.
