<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 at15 fl above ground level, using 7.0
<br />psf top chord dead load and 7.0 psf bottom chord dead load, in the gable end roof Zone on an occupancy category I,
<br />condition I enclosed building, with exposure C ASCE 7-98 per FBC/ANSI95If end verticals or cantilevers exist, they
<br />are exposed to wind. If porches exist, they are not exposed to wind. The lumber DOL increase is 1.33, and the
<br />plate grip increase is 1.33
<br />3) Ceiling dead load (5.0 pst) on member(s). 3-17,16-17,16-18,7_18
<br />4) Bottom chord live load (40.0 pst) and additional bottom chord dead load (10.0 pst) applied only to room. 12-14,
<br />11-12
<br />5) Provide mechanical connection (by others) of truss to bearing plate capable of withstanding 373 Ib uplift at joint 1
<br />and 376 Ib uplift at joint 9.
<br />6) This truss has been designed with ANSIITPI 1-1995 criteria.
