<br />NOTES
<br />1) This truss has been checked for unbalanced loading conditions.
<br />2) This truss has been designed for the wind loads generated by 130 mph winds at 15 ft above ground level, using 7.0
<br />psf lop chord dead load and 7.0 psf bollom chord dead load, in the gable end roof zone on an occupancy category I,
<br />condilion I enclosed building, with exposure C ASCE 7-98 per FBClANSI95 If end verticals or cantilevers exist,they
<br />are exposed to wind. Ir porches exist, they are not exposed to wind. The lumber DOL increase is 1,33, and the
<br />plale grip increase is 1.33
