moisture content shall be sized according to dimensions of structure and
required structural loads.
Column to Upper Column Connection:
shall show, by test or calculation, the foundation column to upper column
connection to be adequate for all imposed bending and axial forces.
Splashboards are No. 2 or better Southern Pine nominal 2x8 S4S pressure
treated to a net retention of 0.4 pounds per cubic foot with chromated copper
arsenate Type III, Oxide type, in accordance with American Wood Preservers
Association Specification C2.
Sidewall eaveboards shall be 2x6 No. 2 Spruce-Pine- Fir or better, and
shall be beveled on the top edge at the same degree as the roof slope.
Wall girts shall be 2x6 No. 2 Southern Pine, 19% maximum moisture content
spaced approximately 24 to 30 o.c., with all ends bearing into wide face
column. Roof purlins shall be recessed between trusses, on edge, and
attached to trusses with adequate fasteners.
Continuous 2x4 lateral bracing shall be provided as required in truss
specification. All other framing
lumber shall be standard grade or better unless specified differently on plans.
All lumber shall be free of warping, twisting, or splitting.
for Metal Plate Connected Wood Trusses:
lumber used in the design of wood trusses must be cured and graded in accordance
rules. Design stresses allowed are those listed in the current
associations grading rules.
design of wood members must be in accordance with the formulas published in the
Edition of the National
Design Specification for Wood Construction as revised to current date.
connector plates and joint design must conform to specifications as set forth in
1995 edition of
the recommended design practice of the Truss Plate Institute, Inc. entitled Design
Specification for Metal Plate Connected Wood Trusses (TPI-95) as revised to
members and joints must be designed in accordance TPI-95.
All truss design must be
complete and accurate shop drawings bearing the seal of a Professional or
Structural engineer, registered in the project State, and contain the following
Slope or depth, span and spacing of the truss.
Location of all joints.

Bottom chord dead load.
Concentrated loads and their points of application.
Adjustments to lumber and plate design values to include modification
for, as applicable.
Moisture service conditions.
Fire retardant treated wood.
Duration of load.
Each reaction force.
Each axial force (Heel panel axial forces shall not exceed 25,000#).
Lateral bracing requirements:
Top chord brace (roof purlin) spacing.
Bottom chord brace spacing.
Web bracing, as applicable.
Plate type, Thickness or gauge, size; basic plate design value
(specifying gross or net
Value); and the
dimensioned location of each plate except where symmetrically located relative
to the joint interface.
Lumber size, species, and grade for each member.
calculations for bending moments shall be available for the designer.
and Siding Panels:
Metal panels are G-90 (Max-Rib 90) zinc-treated, hot-dipped galvanized or
GALVALUME (Max Rib Ultra) 80,000#/SI minimum yield strength structural grade
sheet steel. The paint process is a Kynar 500/Hylar 5000 Fluropon paint
system. Utilizing the full strength 70% PVDF (fluoropolymer) resin and durable
ceramic pigmentation. Panels shall
be fastened with nails or screws, which are compatible to the panels in both
life expectancy and environmental stability.
All panels will be one piece unless lengths greater than 40 feet are
required or the panels must be shortened to accommodate certain building
features. (GALVALUME is a trademark of the Bethlehem Steel Corporation.
