2) TCLL: ASCE 7-05; Pf=40.0 psf (flat roof snow); Category II; Exp B; Partially Exp.; Ct=1.13) Unbalanced snow loads have been considered for this design. 4) This truss has been designed for greater of min roof live load of 16.0 psf or 2.00 times flat roof load of 40.0 psf on overhangs non-concurrent with other liveloads.5) This truss has been designed for a 10.0 psf bottom chord live load nonconcurrent with any other live loads.6) WARNING: Required bearing size at joint(s) 15, 10 greater than input bearing size.7) Bearing at joint(s) 15, 10 considers parallel to grain value using ANSI/TPI 1 angle to grain formula. Building designer should verify capacity of bearing surface.8) Provide mechanical connection (by others) of truss to bearing plate capable of withstanding 59 lb uplift at joint 15 and 59 lb uplift at joint 10.9) This truss is designed in accordance with the 2009 International Residential Code sections R502.11.1 and R802.10.2 and referenced standard ANSI/TPI 1.
10) "Semi-rigid pitchbreaks including heels" Member end fixity model was used in the analysis and design of this truss.
