SIZING TABLES
General Notes
Bearing Requirements
Tables are based on:
– Uniform loads.
–More restrictive of simple or continuous span. Ratio of short span to long span
should be greater than 0.4 to prevent uplift.
– Roof truss framing with 24" soffits.
– Exterior wall weights of 80 plf, interior 60 plf.
–Deflection criteria of L/360 live load and L/240 total load.
■
■
Tables assume minimum header support to be one trimmer (11⁄2") at each end and
41⁄2" at continuous-span supports.
In Sizing Tables on pages 6 and 7:
(2)Indicates minimum header support to be two trimmers (3") at each end and 71⁄2"
at continuous-span supports.
(3)Indicates minimum header support to be three trimmers (41⁄2") at each end and
111⁄4" at continuous-span supports.
Tables do not consider attic loads acting concurrently with roof or snow loads.
Also see How to Use This Table on page 6 and General Assumptions on page 5.
For additional bearing information, see pages 34 and 36.

SIZING TABLES
1.Determine appropriate Floor Load.
Floor framing length
2.Find the Floor Framing Length that meets or exceeds the sum of Spans 1 and 2
for the supported floor joists. When floor joists are continuous span, Span 1 or 2
cannot be less than 40% of the Floor Framing Length. If floor joists are simple
span (not continuous over the beam), then the Floor Framing Length may be
taken as 80% of Span 1 plus Span 2.

Floor Load Tables
1.Calculate total and live load (neglect beam weight) on the beam or header in
pounds per linear foot (plf).
2.Select appropriate Span (center-to-center of bearing).
3.Scan horizontally to find the proper width, and a depth with a capacity that
exceeds actual total and live loads.
4.Review bearing length requirements to ensure adequacy.

Floor Load Tables
General Notes
■
■
Table is based on:
–Uniform loads (beam weight considered).
–More restrictive of simple or continuous span.
–Deflection criteria of L/240 total load (TL) and L/360 live load (LL).
For live load deflection limits of L/240 or L/480, multiply Live Load L/360 values by
1.5 or 0.75, respectively. The resulting live load must not exceed the total load shown.
Also see How to Use this Table on page 16 and General Assumptions on page 5.

Table is based on:
–Deflection criteria of L/180 total load. For stiffer deflection criteria, use L/240
values for total load deflection.
For door and window applications, Weyerhaeuser recommends using the
L/360 value for a live load deflection limit and the L/240 value for a total
load limit.

300 PLF
Connections are based on NDS® 2005 or manufacturer’s test or code reports.
Use specific gravity of 0.5 when designing lateral connections.
Values listed are for 100% stress level. Increase 15% for snow-loaded roof
conditions or 25% for non-snow roof conditions, where code allows.
Bold Italic cells indicate Fastener Pattern must be installed on both sides. Stagger
fasteners on the second side so they fall halfway between fasteners on the first side.
Verify adequacy of beam in allowable load tables on pages 16–33.
7" wide beams should be side-loaded only when loads are applied to both sides of
the members (to minimize rotation).
Minimum end distance for bolts and screws is 6".
Beams wider than 7" require special consideration by the design professional
of record.

Assembly F
415 PLF
First, check the allowable load tables on pages 16–33 to verify that three pieces
can carry the total load of 715 plf with proper live load deflection criteria.
Maximum load applied to either outside member is 415 plf. For a 3-ply, 13⁄4"
assembly, two rows of 10d (0.128" x 3") nails at 12" on-center is good for only
280 plf. Therefore, use three rows of 10d (0.128" x 3") nails at 12" on-center
(good for 415 plf).
Alternative: Two rows of 1⁄2" bolts or 1⁄4" x 31⁄2" SDS screws at 19.2" on-center.

Multiple pieces can be nailed or bolted together to
form a header or beam of the required size, up to a
maximum width of 7"
(1)10d nails are 0.128" diameter; 12d–16d nails are 0.148"–0.162" diameter; screws are SDS, SDW, WS, or TrussLOK™.
(2)An additional row of nails is required with depths of 14" or greater.
When fasteners are required on both sides, stagger fasteners on the second side so they fall halfway between
fasteners on the first side.

General Notes
■
■
Hanger
capacity may be more or less than that of the supported member;
therefore, check both the hanger and the beam capacities.
1⁄16" clearance (1⁄8" maximum) between the end of the beam or header and
Leave
its support member or hanger.
Header Assumptions
■
■
Hangers to be supported by headers of TimberStrand® LSL, Microllam® LVL,
Parallam® PSL, Douglas fir, southern pine, or spruce-pine-fir.
■
Face mount hangers to be supported by 1¾" width headers, minimum.
Nailing Requirements
Fill all round and positive-angle nail holes with the proper nails.
–10d x 1½" nails are 0.148" dia. by 1½" long.
–10d nails are 0.148" dia. by 3" long.
–16d nails are 0.162" dia. by 3½" long.
–For USP: 16d R.S. nails are (9 gauge) 0.148" dia. by 3½" long ring-shank nails.
■
When using top mount hangers in back-to-back applications, ensure that the
supporting beam width is adequate to prevent hanger interference.

We Can Help You Build Smarter
You want to build solid and durable structures—we want to help. Weyerhaeuser
provides high-quality building products and unparalleled technical and field
assistance to support you and your project from start to finish.
Floors and Roofs: Start with the best framing components in the industry: our
Trus Joist® TJI® joists; TimberStrand® LSL rim board; and TimberStrand® LSL,
Microllam® LVL, and Parallam® PSL headers and beams. Pull them all together
with our self-gapping and self-draining Weyerhaeuser Edge Gold™ floor panels and
durable Weyerhaeuser roof sheathing.
Walls: Get the best value out of your framing package—use TimberStrand® LSL
studs for tall walls, kitchens, and bathrooms, and our traditional, solid-sawn
lumber everywhere else. Cut down installation time by using TimberStrand® LSL
headers for doors and windows, and Weyerhaeuser wall sheathing with its handy
two-way nail lines. Use our TJ® Shear Brace for extra support in walls with large
openings or in high wind or seismic areas.
Software Solutions: Whether you are a design professional or lumber dealer,
Weyerhaeuser offers an array of software packages to help you specify individual
framing members, create cut lists, manage inventories—even help you design a
complete structural frame. Contact your Weyerhaeuser representative to find out
how to get the software you need.
Technical Support: Need technical help? Weyerhaeuser has one of the largest
networks of engineers and sales representatives in the business. Call us for help,
