Why Choose Trus Joist® Beams, Columns, and Headers?
• Dependable 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 that 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 nationwide
network of distributors and dealers. For

General Assumptions for Trus Joist® Residential
Beams
■
■
■
Specified strengths and factored resistances are based on Limit States Design per
CSA O86-O9.
Lateral support is required at bearing and along the span at 24" on-centre,
maximum.
Bearing lengths are based on each product’s bearing resistance for applicable
grade and orientation.
■
All members 7¼" and less in depth are restricted to a maximum deflection of 5⁄16".
■
Beams that are 1¾" x 16" and deeper require multiple plies.
■
No camber.
■
Plank Orientation
Beams and columns must remain straight to within 5L2⁄4608 (in.) of true alignment.
L is the unrestrained length of the member in feet.
For applications not covered in this guide, contact your Weyerhaeuser representative.
See pages 16 –18 for fastening multiple-member beams.
TimberStrand ® LSL, Microllam ® LVL, and
untreated Parallam ® PSL are intended for
dry-use applications

How to Use This Table
1. Calculate the factored and unfactored total load (TL) (neglect beam weight)
and the unfactored live load (LL) on the beam or header in pounds per linear
foot (plf).
2. Select appropriate Span (centre-to-centre of bearing).
3. Scan horizontally to find the proper width and a depth that has a capacity that
meets or exceeds actual 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/360 live load (LL) and L/240 total load (TL).
For a live load deflection limit of L/480, multiply Unfactored Resistance (LL)
by 0.75. For a total load limit of L /180 multiply Unfactored Resistance (TL) by
1.33. The resulting loads must not exceed the Total Factored Resistance shown.
Also see How to Use This Table on page 6 and General Assumptions on page 5.

How to Use This Table
1. Calculate the factored and unfactored total load (TL) (neglect beam weight)
and the unfactored live load (LL) on the beam or header in pounds per linear
foot (plf).
2. Select appropriate Span (centre-to-centre of bearing).
3. Scan horizontally to find the proper width and a depth that has a capacity that
meets or exceeds actual loads.
4. Review bearing length requirements to ensure adequacy.
Also see General Notes on page 9.

General Notes
■
■
Table is based on:
– Uniform loads (beam weight considered).
– More restrictive of simple or continuous span.
– Deflection criteria of L/360 live load (LL) and L/240 total load (TL).
For a live load deflection limit of L/480, multiply Unfactored Resistance (LL)
by 0.75. For a total load limit of L /180 multiply Unfactored Resistance (TL) by
1.33. The resulting loads must not exceed the Total Factored Resistance shown.
Also see How to Use This Table on page 8 and General Assumptions on page 5.

How to Use This Table
1. Calculate the factored and unfactored total load (TL) (neglect beam weight)
and the unfactored live load (LL) on the beam or header in pounds per linear
foot (plf).
2. Select appropriate Span (centre-to-centre of bearing).
3. Scan horizontally to find the proper width and a depth that has a capacity that
meets or exceeds actual loads.
4. Review bearing length requirements to ensure adequacy.
Also see General Notes on page 11.

General Notes
■
■
Table is based on:
– Uniform loads (beam weight considered).
– More restrictive of simple or continuous span.
– Deflection criteria of L/360 live load (LL) and L/240 total load (TL).
For a live load deflection limit of L/480, multiply Unfactored Resistance (LL)
by 0.75. For a total load limit of L/180 multiply Unfactored Resistance (TL) by
1.33. The resulting loads must not exceed the Total Factored Resistance shown.
Also see How to Use This Table on page 10 and General Assumptions on page 5.

General Notes
■
Minimum bearing length: 11⁄2" at ends, 31⁄2" at intermediate supports.
■
Bearing across full beam width required.
■
Interpolation between reaction loads is permitted for determining bearing lengths.
■
Bearing lengths based on the following factored bearing resistances:
– 1.3E TimberStrand ® LSL: 990 psi; 630 psi for plank orientation.
– 1.55E TimberStrand ® LSL: 1,165 psi.
– 2.0E Microllam ® LVL: 1,090 psi.
– 2.0E Parallam ® PSL: 1,090 psi.

Uniform Load Design Example
Connections are based on Limit States Design per CSA O86-09.
Use specific gravity of 0.5 when designing lateral connections.
Values listed are for standard term loading.
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 6–11.
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.
435 PLF
625 PLF
First, check load tables on pages 6–11 to verify that three pieces can carry
the total factored load of 1,060 plf with proper live load deflection criteria.
Total factored load = (1.25 x dead load) + (1.5 x live load). Maximum
factored load applied to either outside member is 625 plf. For an assembly
of three 1¾" plies (Assembly B), two rows of 10d (0.128" x 3") nails at 12"
on-centre is good for only 430 plf. Therefore, use three rows of 10d (0.128" x
3") nails at 12" on-centre (good for 650 plf).
Alternatives: Two rows of 1⁄2" bolts or 5" TrussLOK-EWP™ screws at 19.2"
on-centre.

Point Load Design Example
First, verify that three plies of 1¾" x 14" beam material is capable of
supporting the factored 3,000 lb point load, as well as all other loads applied.
The factored 3,000 lb point load is being transferred to the beam with a face
mount hanger. For an assembly of three 1¾" plies, six 5"-long TrussLOK-EWP™
screws are good for 3,295 lbs with a face mount hanger.

1. Unfactored live load:
Case 2: 1.0 x 360 + 0.5 x 600 = 660 plf
Case 3: 1.0 x 600 + 0.5 x 360 = 780 plf
Therefore use Case 3 at 780 plf
2. Unfactored total load:
For Cases 2 and 3:

Therefore a 3½" x 117⁄8" 1.55E TimberStrand® LSL header is acceptable. The beam
requires 2.6" of bearing at end supports and 6.5" of bearing at intermediate support.
Next, calculate design loads per 2010 NBCC load combinations (primary load and
companion load action).

Tables are based on:
– Solid, one-piece column members used in dry-service conditions.
– Bracing in both directions at column ends.
– CSA O86-09.
– Simple columns with axial loads only. For side loads or other combined bending and axial loads, see the
CSA O86-09 provisions.
– KD = 1.0, where the specified snow or live load is greater than the specified dead load. For other load cases,
use Weyerhaeuser software.

Elevated Column Base
Factored resistances have been adjusted to accommodate the worst case of the following eccentric conditions:
1⁄6 of column thickness (first dimension) or 1⁄6 of column width.
Beams and columns must remain straight to within 5L2⁄4608 (in.) of true alignment. L is the unrestrained length
of the member in feet.

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.
