ProDucT linE

• Integri-Lam™ LVL should be stored lying flat and protected

from the weather.

• Keep the material above ground to minimize

the absorption of ground moisture and allow

circulation of air.

• Integri-Lam™ LVL is for use in covered, dry conditions only.

Protect from the weather on the job site both before and

after installation.

• Except for cutting to length, Integri-Lam™ LVL shall not be

cut, drilled or notched. Heel cuts may be possible. Contact

your Alliance Lumber representative.

• Do not install any damaged LVL.

You’ve probably been building with traditional sawn

lumber beams and headers for as long as you’ve been

building. Now through advances in technology and

design, there is a better choice – Integri-Lam™ LVL

headers and beams. They are simply a better alternative

than traditional sawn lumber pieces.

Work with a stronger, stiffer, more consistent and more

predictable building material. Compared with similar

sized sections, our Integri-Lam™ LVL headers and

beams can support heavier loads and allows greater

spans than conventional lumber.


MAXIMUM STRINGER RUN

GENERAL NOTES: 1. Verify compliance with the local building code. 2. Table values are limited by deflection equal to L/360 at live load or L/240

at total load.3. For other design loads, stair constructions or attachment details, consult

with the project designer or engineer of record.

4. Stringers are unstable until treads are installed.5. To minimize squeaks, install treads with panel adhesive in addition to nails

or screws.6. Stringers shall be separated from concrete or masonry in accordance with

the building code.

INTEGRI-LAM PROPERTIES1.5E-2250F Integri-Lam Allowable Design Stresses(1) Modulus of Elasticity E = 1,500,000 psi(2)

bending fb = 2,250 psi(3)(4)

Horizontal Shear (joist) Fv = 230 psi compression Perpendicular to grain (joist) fc⊥ = 750 psi(2) compression Parallel to grain fc = 1,950 psi

(1) These allowable design stresses apply to dry service conditions.

(2) No increase is allowed for load duration.

(3) Multiply by (12/d)1/5 where d = depth of member (in).

(4) A factor of 1.04 may be applied for repetitive members as defined in the National Design Specification® for Wood Construction.

notes:1. The minimum required bearing length is 1Z\x”.2. Duration of load factors may not be applied to bearing

length requirements.3. All Integri-Lam beams require support across their full width.4. All Integri-Lam beams require lateral support at bearing points.

5. Use these values when the Integri-Lam beam is supported by a wall plate, sill plate, timber or built-up girder.

6. Use these values when the Integri-Lam beam is supported by the end of a column or connection hardware.

7. The support member must be sized to carry the load from the Integri-Lam beam.

BEARING DETAILS

notes:1. This detail applies only to uniformly loaded, simple and multiple span

beams. Cantilevered beams and beams that carry concentrated loads are outside the scope of this detail.

2. Square and rectangular holes are not permitted.3. Round holes may be drilled or cut with a hole saw anywhere within the

shaded area of the beam.4. The horizontal distance between adjacent holes must be at least two times

the size of the larger hole. This restriction also applies to the location of access holes relative to bolt holes in multi-ply beams.

5. Do not drill more than three access holes in any four foot long section of beam.

6. The maximum round hole diameter permitted is:

Integri-Lam Beam depth 5Z\x” 7Z\v” 9Z\x” to 24”maximum Hole diameter 1Z\,” 1Z\x” 1Z\x”

7. These limitations apply to holes drilled for plumbing or wiring access only. The size and location of holes drilled for fasteners are governed by the provisions of the National Design Specification® for Wood Construction.

8. Beams deflect under load. Size holes to provide clearance where required.

BEam-to-BEam connEctIon

Make sure hanger capacity is appropriate for each application. Hangers must be properly installed to accommodate full capacity.

3b BEarIng on Wood coLumn

Verify the required bearing area and the ability of the supporting column member to provide adequate strength.

3c BEarIng on stEEL coLumn

Verify the required bearing area and the ability of the supporting column member to provide adequate strength.

BEarIng on ExtErIor WaLL

Prevent direct contact of Integri-Lam with concrete. Consult local building code for requirements.

notes:

1. Minimum fastener schedule for smaller side loads and top-loaded Integri-Lam beams:

Conditions A, B & C, beams 12” deep or less: 2 rows 3Z\x” x 0.131” at 12” o.c. Conditions A, B & C, beams deeper than 12”: 3 rows 3Z\x” x 0.131” at 12” o.c. Conditions D & E, all beam depths: 2 rows Z\x” bolts at 24” o.c.

2. The table values for nails may be doubled for 6” o.c. and tripled for 4” o.c. nail spacings.

3. The nail schedules shown apply to both sides of a three-ply Integri-Lam beam.

4. The table values apply to common bolts that conform to ANSI/ASME Standard B18.2.1-1981. 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 Integri-Lam beam to the bolt holes must be at least 2” for Z\x” bolts. Bolt holes shall be the same diameter as the bolt.

5. 7” wide Integri-Lam beams must be loaded from both sides and/or top loaded.

6. Integri-Lam beams wider than 7” must be designed by the engineer of record.

7. Load duration factors may be applied to the table values.

ExAMPLE:1.5E Integri-Lam beam loaded from both sides and abovetHrEE 1C\v” PLIEs (condItIon B)1. Use allowable load tables or sizing software to size the Integri-Lam

beam to carry a total load of (300 + 610 + 550) = 1460 plf.2. Refer to the 1.5E Integri-Lam table for beam assembly requirements.

Refer to the Condition B row in the table. Scan across the Condition B row from left to right for a table value greater than 550 plf, which is the greatest side load carried by the beam. The fourth value in the row indicates that 3 rows of 16d common nails at 12” o.c. will accommodate a side load of 570 plf which is greater than the 550 plf required. Use 3 rows of 16d common nails at 12” o.c., from both sides, to assemble the beam.
