<br /> This truss has been chec ked for uniform snow load only,except as noted.
<br /> Dead loads shown include weight of truss. Top chord dead load of 5.0 psf(or less)is not adequate for a shingle roof. Architect to
<br /> verify adequacy of top chord dead load.
<br /> All plates are MT20 plates unless otherwise indicated.
<br /> Provide mechanical connection(by others)of truss to bearing plate capable of withstanding 968 lb uplift at j oint 1 and 968 lb uplift at
<br /> ioint 11.
<br /> "Semi-rigid pitchbreaks including heels"Member end fixity model was used in the analy sis and design of this truss.
<br /> This truss must not be exposed to environments that are corrosive or greater than 19 percent moisture.
