DESIGN LIMITATIONS
3. The Truss Design Drawing is based upon specifications provided
by the Building Designer in accordance with ANS1/TPl1. Neither
the Truss Designer, Eagle, nor an engineer who seals this design
(if any) assumes any responsibility for the adequacy or accuracy
of specifications provided by the Building Designer.
4. The Building Designer is solely responsible for the suitability
based upon the Truss Design Drawing and shall be responsible
for reviewing and verifying that the information shown is in
general conformance with the design of the Building.
5. Each Truss Design Drawing is for the individual building
component (a truss). A seal on the Truss Design Drawing
indicates acceptance of professional engineering responsibility
solely for the individual truss.
6. Each Truss Design Drawing assumes trusses will be suitably
protected from the environment.
HANDLING, INSTALLING, & BRACING
7. Refer to BCSI for handling, installing, restraining and bracing
trusses. Copies can be obtained from the Truss Plate Institute
(TPI), 218 N Lee Street, Suite 312, Alexandria, VA 22314,
www.tpinst.org or SBCA, 6300 Enterprise Lane, Madison, WI
53719, www.sbcindustry.com.
8. Bracing shown on each Truss Design Drawing is for lateral
support of individual truss components only to reduce buckling
lengths. All temporary and permanent bracing, including lateral
load and diagonal or cross bracing, are the responsibility,
respectively, of the erector and Building Designer.
9. Eagle is not responsible for improper truss fabrication, handling,
erection or bracing.
10. Compression chords shall be laterally braced by the roof or floor
sheathing, directly attached, or have purlins provided at spacing
shown, unless noted otherwise.
1. The Truss Design Drawing(s) provided with these General
Notes have been prepared under and are subject to ANSI/TPI1.
Capitalized terms have the meanings provided in ANSI/TPI1.
2. Copies of each Truss Design Drawing shall be furnished to the
installation contractor, Building Designer, Owner and all persons
fabricating, handling, installing, bracing, or erecting the trusses.
MATERIALS & FABRICATION
16. Lumber moisture content shall be 19% or less at the time of
fabrication unless noted otherwise.
17. Lumber used shall be of the species and size, and in all respects,
equal to or better than that specified.
18. Unless expressly noted, the truss designs are not applicable for
use with fire retardant or preservative treated lumber.
19. Plates shall be applied on both faces of truss at each joint and
embedded fully. Knots and wane at joint locations shall be
regulated in accordance with ANSl/TPl1.
20. For a specified plate gauge and grade, the specified size is a
minimum.
21. Connections not shown are the responsibility of others.
22. Adequate support shall be provided to resist gravity, lateral,
uplift loads.
23. For 4X2 truss orientation, locate plates 0 - 1/16” from outside the
edge of the truss.
24. Fabrication of truss shall be in accordance with ANSI/TPI1.
OTHER NOTES
25. Camber is a non-structural consideration and is the responsibility
of truss fabricator.
26. Do not cut or alter any truss member or plate without prior

Loads
1) This truss has been designed for the effects of balanced (41.6 psf) and unbalanced sloped roof snow loads in accordance with ASCE7 - 10 with the following user
defined input: 60 psf GSL, Terrain B, Exposure (Ce = 0.9), Risk Category II (I = 1.00), Thermal (Ct = 1.10), DOL = 1.15. Ventilated. If the roof configuration
differs from hip/gable, Building Designer shall verify snow loads.
2) This truss has been designed to account for the effects of ice dams forming at the eaves.
3) This truss has been designed for the effects of wind loads in accordance with ASCE7 - 10 with the following user defined input: 115 mph (Factored), Exposure
B, Enclosed, Gable/Hip, Risk Category II, Overall Bldg Dims 25 ft x 60 ft, h = 15 ft, End Zone Truss, Both end webs considered. DOL = 1.60

Notes
1) Unless noted otherwise, do not cut or alter any truss member or plate without prior approval from a Professional Engineer.
2) Gable requires continuous bottom chord bearing.
3) Gable webs placed at 24 " OC, U.N.O.
4) Attach gable webs with 1x4 20ga plates, U.N.O.
5) Bracing shown is for in-plane requirements. For out-of-plane requirements, refer to BCSI-B3 published by the SBCA.
6) The fabrication tolerance for this roof truss is 10 % (Cq = 0.90).
7) A creep factor of 1.00 has been applied for this truss analysis.
8) Due to negative reactions in gravity load cases, special connections to the bearing surface at joints 10, 16 may need to be considered.
9) Listed wind uplift reactions based on MWFRS & C&C loading.
