Why Choose Trus Joist® Beams, Columns, and Headers?
•Reliable performance
•Consistent quality and dependable uniformity
•Flexible solutions for your beam and header needs
•Backed by a limited product warranty
Using advanced technology, Weyerhaeuser manufactures engineered lumber that
is consistently straight and strong, and resists bowing, twisting, and shrinking. That
means less waste, easier installation, and higher design values for starters; plus
fewer callbacks, shorter cycle times, more design flexibility, and lower overall installed
cost in the end. Trus Joist® TimberStrand® LSL, Microllam® LVL, and Parallam® PSL
are structural solutions you can count on—guaranteed.
The products in this guide are readily
available through our network of
distributors and dealers. For more
information on other applications or
other Trus Joist® products, contact your
Weyerhaeuser representative.
This guide features Trus Joist® engineered lumber in
the following widths and depths:

maximum.
Bearing lengths are based on each product’s bearing stress for applicable grade and
orientation.

Floor Load Tables
How to Use This Table
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.
Also see General Notes on page 7.

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 6 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.

General Notes
■
Minimum bearing length: 11⁄2" at ends, 31⁄2" at intermediate supports.
■
Bearing across full beam width is required.
■
Interpolation between reaction loads is permitted for determining bearing lengths.
■
Bearing lengths based on the following bearing stresses:
– 1.3E TimberStrand ® LSL: 710 psi; 635 psi for plank orientation.
– 1.55E TimberStrand ® LSL: 900 psi.
– 2.0E Microllam ® LVL: 750 psi.
–2.2E Parallam ® PSL: 625 psi.

Uniform Load Design Example
300 PLF
First, check allowable load tables on pages 6 – 23 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 an assembly of three
13⁄4" plies (Assembly B), two rows of 10d (0.128" x 3") nails
at 12" o.c. center is good for only 280 plf. Therefore, use three
rows of 10d (0.128" x 3") nails at 12" o.c (good for 415 plf).
Alternative: Two rows of 1⁄2" A307 bolts or 31⁄2" USP WS
screws at 19.2" on-center.

General Notes for Side-Loaded Beam Tables
Connections are based on NDS® 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.
When fasteners are required 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 6–23.
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.

First, verify that a 3-ply, 1¾" x 14" beam can support a 3,000 lb
point load and all other loads applied. The 3,000 lb point load is
being transferred to the beam with a face mount hanger. For an
assembly of three 1¾" plies (Assembly B), six 3½" SDS screws
are good for 3,060 lbs with a face mount hanger.

General Notes
■
Capacities shown cannot be adjusted for duration of load.
■
Connector capacities assume a beam material with a minimum perpendicular-to-grain bearing of 625 psi.
■
■
Column
Connector capacities may be more than the column capacity; therefore, check both the connector and the column capacity
and use the lower capacity.
Other connectors may be available. Capacities may vary depending on orientation of member. Contact the hanger
manufacturer for more information.

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 GoldTM 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.
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,
and a skilled member from our team of experts will answer your questions and work
with you to develop solutions that meet all your structural framing needs.
