ENVIRONMENTAL CHOICE In choosing wood as a construction material, you are choosing a building material that is made from renewable resources. Due to sustained forest practices, the volume of wood in our forests has actually increased by 35% over the last 25 years. When considering total environmental impact including extraction of raw materials, energy required during manufacturing, emissions from manufacturing operations, and energy efficiency of buildings, IB's group of engineered wood products are among the most environmentally friendly building products available. See the IB website, www.ibewp.com, for the latest information on meeting green building standards using IB products.

ENGINEERED WOOD PRODUCTS Engineered wood products, and specifically laminated veneer lumber (LVL), offer advantages over conventional lumber products that result in savings for the builder and long-term performance benefits for the homeowner. IB MAX-CORE LVL is available in 2.0E - 3100F b. IB offers depths up to 24 inches and lengths up to 52 feet. Our water resistant coating will protect the LVL during warehousing and construction. The standard natural finish accepts good quality structural adhesives. IB MAX-CORE LVL can be built up on site for two-ply, three-ply and four-ply applications. IB MAX-CORE LVL is recognized as an innovative solution to the building industry s floor and roof framing needs. DESIGNED TO PERFORM IB MAX-CORE LVL is made from ultrasonically graded veneers assembled longitudinally (all plys in the same direction) to yield maximum strength. Top grade veneers with few imperfections are used. Electronic scanners are used to identify defects and a clipper removes them. The high-quality veneers, which offer maximum strength and uniformity, are then laid up with waterproof adhesives and pressed into a billet. A unique combination of heat and pressure ensures a reliable glue line. IB MAX-CORE LVL can be used as single ply or as assembled beams which are exceptionally strong, straight and solid. IB MAX-CORE LVL is available in custom lengths and depths, further increasing its value to builders. RELIABLE DESIGN/ PRODUCT CERTIFICATION IB MAX-CORE LVL bending values can be incorporated with a wide variety of design softwares. IB MAX-CORE LVL is certified under APA program based on ASTM 5456 standard. 4 INTERNATIONAL BEAMS U.S. LVL DESIGN MANUAL OCTOBER 2016

ENGINEERING RESPONSIBILITY POSITION STATEMENT IB manufactures and distributes proprietary engineered wood products (EWP). We have full-time professional engineers on staff. Our engineers are active in the development, manufacture, and marketing of IB products. Our engineering services are limited to supporting the engineered wood components that we manufacture and distribute (IB MAX-CORE LVL, IB MAX-CORE I-Joist, and IB MAX-CORE Rimboard). We review and seal component calculations produced on our software, and provide advice on proper installation. The design professional of record (Engineer or Architect) is responsible for design of the overall structure, global lateral stability, and interaction of various components of the structure. The limited scope of engineering services provided by IB does not replace the need on any project for a design professional of record. INTERNATIONAL BEAMS U.S. LVL DESIGN MANUAL OCTOBER 2016 5

NOTES FOR USE OF ALLOWABLE UNIFORM FLOOR AND ROOF LOADS TABLES 1. The load tables have been developed using the provisions of National Design Specification for Wood Construction 2015 Edition and the allowable stress design properties provided in APA Product Report PR-L318. 2. The load tables are not intended to substitute the provision of services by a structural engineer according to local project requirements. For any beam configurations that do not correspond to the assumptions of this table, the services of a structural engineer may be required. 3. The load tables are based on the maximum uniform load for floor (100% duration) or roof (115% duration) applications in residential buildings, using the most restrictive of either simple spans or continuous spans of equal length. The span length is measured from the center of the supports. The loads shown in the tables may be added to the self-weight of the beam. 4. IB MAX-CORE LVL must only be used in dry service conditions where the moisture content of the LVL will be maintained at 16% or less. 5. IB MAX-CORE LVL require lateral support at beam bearing points and continuous lateral support of the compression edge of the beam. 6. All single ply beams are limited to a depth of 14 maximum. Plies that are 16 or deeper must be used in multiple-ply applications. 7. Deflection limits must be verified with local building code and project requirements. The deflection limits used in the tables for floors (100% duration) are L/360 for live load and L/240 for total load. The deflection limits used in the tables for roofs (115% duration) are L/240 for live load and L/180 for total load. 8. To use the tables, the user must check that both the live load and the total load values listed are not exceeded for a given span. Where the symbol is shown for the allowable live load, the total load governs the design, unless the user has chosen a more stringent limit for the live load deflection (see notes 9 and 10). 9. To apply live load deflection limits of L/480 or L/600 for floor applications (100% duration), multiply the allowable load in the Live Load L/360 row by 0.75 or 0.5 respectively. 10. To apply live load deflection limits of L/360 or L/480 for roof applications (115% duration), multiply the allowable load in the Live Load L/240 row by 0.67 or 0.5 respectively. 11. If the actual span of the beam falls in between two span lengths in the SPAN column, use the allowable loads given for the greater span length. 12. The load tables include the repetitive load factor (Cr=1.04) for beams with three plies or more. 13. The load tables include the effect of allowable holes in the middle 1/3 of the depth and the middle 1/3 of the span, all according to the guidelines provided in this product manual. 14. The bearing conditions in the load table assume bearing across the full width of the beam, and a bearing material that has a bearing strength equivalent or greater than IB MAX-CORE LVL (520 psi). The load tables include an assumed maximum available bearing length of 4 ½ at the exterior supports of the beam. 15. For applications where the total load does not exceed the value given in the table, the length of bearing values may be reduced proportionately.

The minimum bearing length table has been developed using the provisions of National Design Specification for Wood Construction 2015 Edition and the allowable stress design properties provided in APA Product Report PR-L318. 2. Minimum required bearing length is 1 ½ at beam end supports and 3 ½ at interior supports. 3. Bearing across the full width of the beam is required. 4. Bearing lengths are based on an allowable bearing stress perpendicular to grain of 520 psi for IB MAX-CORE LVL. The structural adequacy of the support material or member must also be verified by the user. 5. Bearing lengths are based on dry service conditions only. 6. No decrease in bearing length is permitted for duration of load. 20 INTERNATIONAL BEAMS U.S. LVL DESIGN MANUAL OCTOBER 2016
NOTES FOR ALLOWABLE UNIFORM FLOOR AND ROOF LOADS (PLF) 1. Deflection limits must be verified with local building code and project requirements. The deflection limits used in the tables for floors (100% duration) are L/360 for live load and L/240 for total load. The deflection limits used in the tables for roofs (115% duration) are L/240 for live load and L/180 for total load. 2. The bearing conditions in the load table assume bearing across the full width of the beam, and a bearing material that has a bearing strength equivalent or greater than IB MAX-CORE LVL (520 psi). The load tables include an assumed maximum available bearing length of 4 ½ at the exterior supports of the beam. INTERNATIONAL BEAMS U.S. LVL DESIGN MANUAL OCTOBER 2016 21
