<br />TRUSS NOTES:
<br />
<br />1. WOOD TRUSS ERECTOR SHALL PROVIDE BRACING ACCORDING TO ANSI/TPl-2002
<br />(TRUSS PLATE INSTITUTE) NOTE THAT THE COMBINED WIND AREA IS GREATER BEFORE THE ROOF SHEATHING is APPLIED, AND
<br />BRACING SHALL THEREFORE BE INSTALLED AS THE TRUSSES ARE ERECTED. INADEQUATE BRACING IS THE MOST COMMON CAUSE OF ACCIDENT
<br />IN WOOD TRUSS CONSTRUCTION. FULL BUNDLES OF PLYWOOD SHALL NOT BE PLACED ON TRUSSES. THIS CONSTRUCTION LOAD SHOULD BE LIMITED
<br />TO 8 SHEETS OF PLYWOOD ON ANY PAIR OF TRUSSES & SHALL BE LOCATED ADJACENT TO THE SUPPORTS. NO EXCESS CONCENTRATION OF ANY
<br />CONSTRUCTION MATERIAL (SUCH AS GRAVEL OR SlINGLES) SHALL BE PLACED ON THE TRUSSES IN ANY ONE AREA THEY SHALL BE SPREAD OUT
<br />EVENLY OVER A LARGE AREA SO AS TO AVOID OVEI~LOADING ANY ONE TRUSS.
<br />2. ALL BRACING (DB,CB,BB) SHOWN ABOVE SHALL BI IN ADDITION TO CONTINUOUS LATERAL BRACING SPECIFIED BY THE TRUSS MANUFACTER ALL
<br />LATERALBRACING SPECIFIED BY TRUSS MANUF. Sr!ALL HAVE ADDITIONAL DIAGONAL BRACES AT 20'-0" O.C. MAXIMUM.
<br />3. ALL BRACES SHALL BE 2X4 NOMINAL DIMENSION I UMBER & SHALL BE ATTACHED W/ 2-16D NAILS AT EACH TRUSS INTERSECTION.
<br />4. ADDITIONAL BOTTOM CHORD BRACING SHALL BE I~STALLED AS REQUIRED BY TRUSS DESIGN WHEREVER ADEQUATE STRUCTURAL CEILING ARE \OT
<br />ATTACHED DIRECTLY TO THE BOTTOM CHORD OF Tf E TRUSS.
<br />5. PROVIDE TRUSS BLOCKING AT ALL TRUSS BEARIN(i SUPPORTS WHERE TRUSS DEPTH EXCEEDS STANDARD HEEL HEIGHT.
