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 products provide flatter, quieter floors and consequently, the builder can expect happier customers with significantly fewer call backs.

All projects related to the application field of part 4 of the National Building Code (NBCC) shall take into consideration the effects of concentrated loads, as stipulated in article 4.1.6.3. When a project corresponds to the application field of part 4, the designer shall verity the effect of a concentrated load on the joists used. The NBCC has a table in section 4.1.6.10 of concentrated loads which shall be used according to the anticipated use of the floor. Given that possibilities are numerous, the span tables listed in this book do not take into consideration the effects of concentrated loads.

Allowable Holes

1. Design values apply to common bolts that conform to ASTM A307. 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 least 2" for 1/2" bolts. 2. The nail schedules shown apply to both sides of a three member beam. 3. 4-ply beams must be top-loaded or loaded from both sides. 4. Bolt holes shall not be greater than 1/16 of the bolt diameter. 5. An equivalent specific gravity of 0.5 may be used when designing specific connections with VERSA-LAM. 6. Beams wider than 7" must be designed by the professional engineer of record. 7. Connection design is based on CSA O86-01 8. FastenMaster TrussLok, Simpson Strong-Tie SDS, and member VERSA-LAM beams, contact Boise EWP Engineering for further information.

Center-to-center Spacing

Square and rectangular holes are not permitted. Round holes may be drilled or cut with a hole saw anywhere within the shaded area of the beam. 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. Do not drill more than three access holes in any four feet long section of beam. These limitations apply to holes drilled for plumbing or wiring access only. The size and location of holes drilled for fasteners are under the regulations of the CSA O86-01 Engineering Design in Wood. Beams deflect under load. Size holes to provide clearance where required. This hole chart is valid for beams supporting uniform load only. For beams supporting concentrated loads or for beams with larger holes, contact Boise Cascades Engineering Department.

The maximum round hole diameter permitted is: Beam Depth 51/2" 71/4" Greater than 71/4" Maximum Round Hole 3/4" 1" 2"

Total Factored Load values are limited by shear or moment. Total Load values are the capacity of the beam in addition to its own weight. Unfactored Live Load values are limited by deflection equal to L / 360. For deflection limited to L / 480, multiply live load value by 0.75 (recommended for less vibrations). All 3 loading cases must be checked.Where a Live Load value is not shown, the Factored Total Load value will control. Table values represent the most restrictive of simple or continuous span beams applications and assume an uniform loading. Span is measured center to center of the supports. Analyze continuous span beams with the WoodWorks Sizer for Boise Cascade 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 Factored 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 Factored Total Load and Allowable Unfactored Live and Total Load values. Minimum Required Bearing Lengths remain the same for any number of plies. 1 3/4" members deeper than 14" are recommended to be used as multiple-member beams. See details for proper connection. 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 WoodWorks Sizer for Boise Cascade software. Live Load Values in Yellow gives a Live Deflection between 3/4" and 1". Live Load Values in Green gives a Live Deflection between 1/2" and 3/4".

This table assumes a maximum roof slope of 12 / 12. This table has been established using a Live Load deflection equal to L / 360 and a Total Load deflection limit equal to L / 240. This table assumes uniform loads and simple span roof joists. Table values represent the most restrictive of simple or continuous span beam applications. Span is measured center to center of the supports. Analyze continuous span beams with the WoodWorks Sizer for Boise Cascade 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.

1. Design values apply to common bolts that conform to ASTM A307. 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 least 2" for 1/2" bolts. 2. The nail schedules shown apply to both sides of a three member beam. 3. 4-ply beams must be top-loaded or loaded from both sides. 4. Bolt holes shall not be greater than 1/16 of the bolt diameter. 5. An equivalent specific gravity of 0.5 may be used when designing specific connections with VERSA-LAM. 6. Beams wider than 7" must be designed by the professional engineer of record. 7. Connection design is based on CSA O86-01 8. 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.
