An Introduction to VERSA-LAM® Products
When you specify VERSA-LAM® laminated veneer
headers/beams, you are building quality into your
design. They are excel­lent as floor and roof framing
supports or as headers for doors, windows and garage
doors and columns.
Because they have no camber, VERSA-LAM®
LVL products provide flatter, quieter floors, and
consequently, the builder can expect happier
customers with significantly fewer call backs.
VERSA-LAM® Beam Architectural Specifications
Scope: This work includes the complete
furnishing and installation of all VERSALAM ® beams as shown on the drawings,
herein specified and necessary to
complete the work.
Materials: Southern Pine or Douglas
fir veneers, laminated in a press with
all grain parallel with the length of the
member. Glues used in lamination are
phenol formaldehyde and isocyanate
exterior-type adhesives which comply with
ASTM D2559.
Design: VERSA-LAM ® beams shall be
sized and detailed to fit the dimensions
and loads indicated on the plans. All
designs shall be in accor­dance with allow­
able values developed in accordance with
ASTM D5456 and listed in the governing
code evaluation service's report and
section properties based upon standard
engineering principles. Verification of
design of the VERSA-LAM ® beams by
complete calculations shall be available
upon request.
Storage and Installation: VERSA-LAM®
beams, if stored prior to erection, shall be
stored on stickers spaced a maximum of
15 ft. apart. Beams shall be stored on a
dry, level surface and protected from the
weather. They shall be handled with care
so they are not damaged.
Drawings: Additional drawings
showing layout and detail necessary
for determining fit and placement in the
buildings are (are not) to be provided by
the supplier.
VERSA-LAM® beams are to be installed in
accordance with the plans and Boise EWP's
Installation Guide. Temporary con­struction
loads which cause stresses beyond design
limits are not permitted. Erection bracing
shall be provided to assure adequate lateral
support for the individual beams and the
entire system until the sheathing material
has been applied.
Fabrication: VERSA-LAM ® beams
shall be manu­factured in a plant
evaluated for fabrication by the governing
code evaluation service and under the
supervision of a third-party inspection
agency listed by the corresponding
evaluation service.
Codes: VERSA-LAM ® beams shall
be evaluated by a model code evaluation
service.

1.Beams wider than 7" must be designed by the engineer of record.
2.All values in these tables may be increased by 15% for snow-load
roofs and by 25% for non-snow load roofs where the building
code allows.
3.Use allowable load tables or BC CALC® software to size beams.
4.An equivalent specific gravity of 0.5 may be used when designing
ALLJOIST® Specifier Guide - UNITED STATES
specific connections with VERSA-LAM ®.
5.Connection values are based upon the 2005 NDS.
6. FastenMaster TrussLok, Simpson Strong-Tie SDS, and USP
WS screws may also be used to connect multiple member
VERSA-LAM ® beams, contact Boise EWP Engineering for
further information.
Designing Connections for
Multiple Versa-Lam® Members
When using multiple ply VERSA-LAM® beams to create a wider
member, the connection of the plies is as critical as determining the
beam size. When side loaded beams are not connected properly,
the inside plies do not support their share of the load and thus the
load‑carrying capacity of the full member decreases significantly. The
following is an example of how to size and connect a multiple-ply
VERSA-LAM® floor beam.
Given: Beam shown below is supporting residential floor load
(40 psf live load, 10 psf dead load) and is spanning 16'-0".
Beam depth is limited to 14".
Hangersnotshown
forclarity
14'
18'
Find: A multiple 1¾" ply VERSA-LAM ® that is adequate to support the
design loads and the member's proper connection schedule.
1. Calculate the tributary width that beam is supporting:
14' / 2 + 18' / 2 = 16'
2. Use PLF tables on page 25-27 of ASG or BC CALC® to size beam.
A Triple VERSA-LAM® 2.0 3100 1¾" x 14" is found to
adequately support the design loads
3. Calculate the maximum plf load from one side
(the right side in this case).
Max. Side Load = (18' / 2) x (40 + 10 psf) = 450 plf
4. Go to the Multiple Member Connection Table, Side-Loaded
Applications, 1¾" VERSA-LAM®, 3 members
5. The proper connection schedule must have a capacity greater than
the max. side load:
Nailed: 3 rows 16d sinkers @ 12" o.c:
525 plf is greater than 450 plf OK
Bolts: ½" diameter 2 rows @ 12" staggered:
755 plf is greater than 450 plf OK

• Total Load values are limited by shear, moment or deflection equal to L/240. Total Load values
are the capacity of the beam in addition to its own weight.
• Live Load values are limited by deflection equal to L/360. Check the local building code for other
deflection limits that may apply.
• Where a Live Load value is not shown, the Total Load value will control.
• Table values represent the most restrictive of simple or multiple span applications. Span is
measured center to center of the supports. Analyze multiple span beams with the BC CALC® soft­
ware if the length of any span is less than half the length of an adjacent span.
• Table values assume that lateral support is provided at each support and continuously along the
top edge and applicable compression edges of the beam.
• Table values for Minimum Required Bearing Lengths are based on the allowable compression

design value perpendicular to grain for the beam and the Total Load value shown. Other design
considerations, such as a weaker support material, may warrant longer bearing lengths. Table
values assume that support is provided across the full width of the beam.
• For 2-ply, 3-ply or 4-ply beams; double, triple or quadruple Allowable Total Load and Allowable
Live Load values. Minimum Required Bearing Lengths remain the same for any number of plies.
• 1¾ inch members deeper than 14 inches are to be used as multiple-member beams only.
• This table was designed to apply to a broad range of applications. It may be possible to exceed
the limitations of this table by analyzing a specific application with the BC CALC® software.

• Total Load values are limited by shear, moment or deflection equal to L/180. Total Load values are the
capacity of the beam in addition to its own weight.
• Live Load values are limited by deflection equal to L/240. Check the local building code for other
deflection limits that may apply.
• Where a Live Load value is not shown, the Total Load value will control.
• Table values represent the most restrictive of simple or multiple span applications. Span is measured
center to center of the supports. Analyze multiple span beams with the BC CALC® soft­ware if the
length of any span is less than half the length of an adjacent span.
• Table values assume that lateral support is provided at each support and continuously along the top
edge and applicable compression edges of the beam.

• Table values for Minimum Required Bearing Lengths are based on the allowable compression design
value perpendicular to grain for the beam and the Total Load value shown. Other design considerations,
such as a weaker support material, may warrant longer bearing lengths. Table values assume that
support is provided across the full width of the beam.
• For 2-ply, 3-ply or 4-ply beams; double, triple or quadruple Allowable Total Load and Allowable Live
Load values. Minimum Required Bearing Lengths remain the same for any number of plies.
• 1¾ inch members deeper than 14 inches are to be used as multiple-member beams only.
• This table was designed to apply to a broad range of applications. It may be possible to exceed the
limitations of this table by analyzing a specific application with the BC CALC® software.

• Total Load values are limited by shear, moment or deflection equal to L/180. Total Load values are the
capacity of the beam in addition to its own weight.
• Live Load values are limited by deflection equal to L/240. Check the local building code for other
deflection limits that may apply.
• Where a Live Load value is not shown, the Total Load value will control.
• Table values represent the most restrictive of simple or multiple span applications. Span is measured
center to center of the supports. Analyze multiple span beams with the BC CALC® soft­ware if the
length of any span is less than half the length of an adjacent span.
• Table values assume that lateral support is provided at each support and continuously along the top
edge and applicable compression edges of the beam.

• Table values for Minimum Required Bearing Lengths are based on the allowable compression design
value perpendicular to grain for the beam and the Total Load value shown. Other design considerations,
such as a weaker support material, may warrant longer bearing lengths. Table values assume that
support is provided across the full width of the beam.
• For 2-ply, 3-ply or 4-ply beams; double, triple or quadruple Allowable Total Load and Allowable Live
Load values. Minimum Required Bearing Lengths remain the same for any number of plies.
• 1¾ inch members deeper than 14 inches are to be used as multiple-member beams only.
• This table was designed to apply to a broad range of applications. It may be possible to exceed the
limitations of this table by analyzing a specific application with the BC CALC® software.

The same properties that make VERSA-LAM® beams great, also make them highly suitable for wood
columns. In VERSA-LAM® columns, you'll find none of the deep checks, cracks or twists that can plague
solid wood columns.

1) Table assumes that the column is braced at column ends only. Effective
column length is equal to actual column length.
2) Allowable loads are based upon one-piece (solid) column members used
in dry service conditions. Contact project's design professional of record
or Boise EWP Engineering for multi-piece column design.
3) Allowable loads are based on an eccentricity value equal to 0.167
multiplied by either the column thickness or width (worst case).
4) Allowable loads are based on axial loaded columns using the design
provisions of the National Design Specification for Wood Construction
(NDS), 2005 edition. For side or other combined bending and axial loads,
see provisions of NDS, 2005 edition.
5) Load values are not shown for short lengths due to loads exceeding
common connector capacities. Load values are not shown for longer
lengths if the controlling slenderness ratio exceeds 50 (per NDS).
6) Lateral loads (wind loading) are not considered in this table.
