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.

1. Design values apply to common bolts that conform
to ANSI/ASME standard B18.21-1981 (ASTM A307
Grades A&B, SAE J429 Grades 1 or 2, or higher).
A washer not less than a standard cut washer
shall be between the wood and the bolt head and
between the wood and the nut. The distance from
the edge of the beam to the bolt holes must be at
N/A
least 2" for ½" bolts and 2½" for ⅝" bolts. Bolt
holes shall be the same diameter as the bolt.
2. The nail schedules shown apply to both sides of a
three-member beam.
3. 7" wide beams must be top-loaded or loaded from
both sides.
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".

1.Beams wider than 7" must be designed by the engineer
of record.
4.An equivalent specific gravity of 0.5 may be used when
designing specific connections with VERSA-LAM®.
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.
5.Connection values are based upon the 2005 NDS.
3.Use allowable load tables or BC CALC® software to
size beams.
6.FastenMaster TrussLok, Simpson Strong-Tie SDW or
SDS, and USP WS screws may also be used to connect
multiple member VERSA-LAM ® beams, contact Boise
Cascade EWP Engineering for further information.

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 pages 5-7 or BC CALC® to size beam.
A Triple VERSA-LAM ® 2.0 2800 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

(1) 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.
(2) 1¾ inch members deeper than 14 inches are to be used as
multiple-member beams only.
• 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 ® 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 compression edge 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.
• 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.

(1) 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.
(2) 1¾ inch members deeper than 14 inches are to be used as
multiple-member beams only.
• 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 ®
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 compression edge 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.
• 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.

• 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 ®
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 compression edge 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.
• 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.

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 Cascade 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.

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®
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 compression edge 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 double 3½" beams, multiply allowable total load and allowable live load values by the
number of plies. Minimum required bearing lengths remain the same for any number of plies.
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.

• 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 double 3½" beams, multiply allowable total load and allowable live load values by the
number of plies. Minimum required bearing lengths remain the same for any number of plies.
• This table was designed to apply to a broad range of applications. It may be possible to exceed

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 compression edge of the beam.
• Table values for Minimum Required Bearing Lengths are based on the allowable compression

• Table values assume that lateral support is provided at each support and continuously along
the compression edge 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.
• 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.

SPAN/LOADING NOTES
- Deflection limited to L/360 live load & L/240 total load.
- Spans based upon a stair limits of 8" max rise and 9" min. run, verify actual required
minimum riser and tread width as required by local building code and amendments.
- Contact Boise EWP Engineering for design assistance on other stair stringer applications
and/or loading.
4'-4"
6'-10"
9'-1"

- Consult governing building code and/or local building official for proper live load per
application.
- Building codes typically restrict stair widths to 44" or greater for stairways serving an
occupant load of 50 or less.
- Maximum total rise between floors is 12'-0" per building codes.

CONSTRUCTION NOTES
• STAIR STRINGERS ARE EXTREMELY UNSTABLE, USE CAUTION
WHEN INSTALLING TREADS. DO NOT ALLOW WORKERS ON
STAIRS UNTIL EACH END OF EACH STRINGER HAS BEEN
PROPERLY ATTACHED AND TEMPORARY TREADS HAVE BEEN
INSTALLED.
• Use subfloor adhesive on all contact surfaces to minimize squeaks.
• Adequate moisture barrier required between stringers and concrete.
• Keep product as dry as possible during construction.
• All wood splits when significant stress is induced across the grain DO NOT apply significant side impact load (e.g., hammer) to
remaining triangle sections of stringers.
• When installing treated wood, use only connectors/fasteners that
are approved for use with the corresponding wood treatment.
• Use fasteners no larger than 8d box nail or #8 wood screw for
attaching standard treads, space no closer than 3" on-center.
