Environmental Choice

Construction details reprinted with permission from the APA - The Engineered Wood Association.

In choosing wood as a construction material, you are choosing the only 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. International Beams’ I-joists are made from two wood products. The flanges are made from small dimension lumber that is sawn from small trees and the tops of larger trees.

The web is a special grade of oriented strand- board that is made from under-utilized wood species. Both components assist in achieving total utilization of each tree harvested.

When considering total environmental impact including extraction of raw materials, energy required during manufacturing, emissions from manufacturing operations, and energy efficiency of buildings, Inter-national Beams group of engineered wood products are among the most environmentally friendly building products available. For details on how IB products can help to meet green building standards, see page 20, or contact International Beams.

Our Guarantee

Our Company

Engineered wood products, and specifically I-joists offer advantages over conventional lumber products that result in savings for the builder and long-term performance benefits for the homeowner.

I-joists are installed using traditional framing tools and fasteners. With long lengths, I-joists are used in multiple span applications, thus reducing cutting, overlapping and material waste at the job site. Also, since I-joists span longer distances than traditional framing lumber, the joist spacing can be wider, resulting in fewer pieces to handle and install.

The wide flanges used in all IB series provide a larger gluing and nailing surface for floor and roof sheathing. These lightweight joists will not twist, warp, or shrink and are more uniform in their dimensions than solid lumber. Our joists are available in depthts from 9½" to 24" and lengths up to 52 feets. For depths less than 18", see our Residential Design Manual or contact International Beams.

International Beams Inc.’s I-joists are recognized as an innovative solution to the building industry’s floor and roof framing needs.

Floor PerformanceOur broad range of I-joists provides the builder with flexibility in joist selection, spacing, and construction detail. Although all values contained in this brochure meet or exceed code requirements, long-term floor performance (comfort) should be considered in all construction projects.

The following suggestions will increase the floor stiffness and reduce floor vibration:

• Using floor deflection of L/480 instead of the code minimum of L/360.• Gluing and nailing the sub-floor to the joists.• Attaching gypsum board to the bottom of the floor.• Decreasing the joist spacing by one increment based on allowable span.• Using full depth I-joist blocking panels at mid span between floor joists.• Using deeper joists.• Using a thicker sub-floor, i.e. ¾" or 7/8".• Attaching strapping at 16" o/c.

Design ServicesDesign and related services include, but are not limited to:

• Beam sizing• Component Framing Layouts• Coordination with architects and builders • On-site review• Pricing • Shipping

These services are generally provided by your local International Beams distributor. There are also local lumber yards, stocking dealers, and design professionals who are familiar with our IB products and may be able to provide some of these design services. If you need help with your design project, please contact International Beams at [email protected], or contact the local distributor indicated on the back cover of this literature.

Engineering Responsibility Position StatementInternational Beams Inc. manufactures and distributes proprietary engineered wood products (EWP).

We have full-time professional engineers (P.Eng.) 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 I-joists, IB LVL, IB Rim Board). We review and seal component calculations produced on our software, and provide advice on proper installation.

The design professional of record (P.Eng. 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 International Beams Inc. does not replace the need on any project for a design professional of record.

NOTES: (a) Allowable spans are applicable to floor construction. LSD load factor of 1.5 is applied to live load and 1.25 to dead load for strength calculations. If partition dead load is not required, the total design dead load of 35 psf may be used for material weight of the floor construction. (b) Allowable spans have been calculated with the CCMC vibration criteria limits only where indicated in the assembly. (c) Deflection limits indicated in the table heading are based on partial composite action with glued and nailed subfloor meeting requirements for APA Span-Rated STURD-I-FLOOR conforming to PRP-108, PS 1, PS 2, CSA 0325, or CSA 0437. Construction adhesive shall meet the requirements given in ASTM D3498 or APA Specification AFG-01. (d) Minimum bearing length shall be 1¾” for end bearing and 3 ½” for interior bearings. Allowable design spans in the table are measured from inside face of bearings for simple spans and from inside face of end bearing to center of interior bearing for continuous spans. (e) Bearing stiffeners are not required when I-joists are used with the spans given in this table, except as required by hanger manufacturers. (f) This span table is based on uniform loads. For applications with other than uniformly distributed loads, or other applications beyond the scope of the indicated design criteria, an engineering analysis may be required based on the use of the design properties accepted in the CCMC 12768-R evaluation report. Design properties are also indicated in table 1 at the front of the design manual. For technical support, contact International Beams (IB) or your local IB distributor. (g) Continuous spans given in the table above are the longest clearspan between bearings for a joist with three bearings. The ratio of the shorter span to the longer spans must be greater than 40%. For two spans with a ratio of between 40% and 76%, provide metal hangers or equivalent to withstand an uplift force at the end of the shorter span. Calculate uplift at the end of the shorter span as follows: factored total load (psf) x joist spacing (inches) x [(shorter span (feet) minus 0.76 x longer span (feet)] divided by 25. For all other applications, consult International Beams.

(c) Deflection limits indicated in the table heading are based on partial composite action with glued and nailed subfloor meeting requirements for APA Span-Rated STURD-I-FLOOR conforming to PRP-108, PS 1, PS 2, CSA 0325, or CSA 0437. Construction adhesive shall meet the requirements given in ASTM D3498 or APA Specification AFG-01. (d) Minimum bearing length shall be 3½" for end bearing and 3 ½” for interior bearings. Allowable design spans in the table are measured from inside face of bearings for simple spans and from inside face of end bearing to center of interior bearing for continuous spans. (e) Bearing stiffeners are required when I-joists are used with the spans given in this table. (f) This span table is based on uniform loads. For applications with other than uniformly distributed loads, or other applications beyond the scope of the indicated design criteria, an engineering analysis may be required based on the use of the design properties accepted in the CCMC 12768-R evaluation report. Design properties are also indicated in table 1 at the front of the design manual. For technical support, contact International Beams (IB) or your local IB distributor. (g) Continuous spans given in the table above are the longest clearspan between bearings for a joist with three bearings. The ratio of the shorter span to the longer spans must be greater than 40%. For two spans with a ratio of between 40% and 76%, provide metal hangers or equivalent to withstand an uplift force at the end of the shorter span. Calculate uplift at the end of the shorter span as follows: factored total load (psf) x joist spacing (inches) x [(shorter span (feet) minus 0.76 x longer span (feet)] divided by 25. For all other applications, consult International Beams.

NOTES: (a) Allowable spans are applicable to floor construction. LSD load factor of 1.5 is applied to live load and 1.25 to dead load for strength calculations. If partition dead load is not required, the total design dead load of 35 psf may be used for material weight of the floor construction. (b) Allowable spans have been calculated with the CCMC vibration criteria limits only where indicated in the assembly. (c) Deflection limits indicated in the table heading are based on partial composite action with glued and nailed subfloor meeting requirements for APA Span-Rated STURD-I-FLOOR conforming to PRP-108, PS 1, PS 2, CSA 0325, or CSA 0437. Construction adhesive shall meet the requirements given in ASTM D3498 or APA Specification AFG-01. (d) Minimum bearing length shall be 3½" for end bearing and 3 ½” for interior bearings. Allowable design spans in the table are measured from inside face of bearings for simple spans and from inside face of end bearing to center of interior bearing for continuous spans. (e) Bearing stiffeners are required when I-joists are used with the spans given in this table. (f) This span table is based on uniform loads. For applications with other than uniformly distributed loads, or other applications beyond the scope of the indicated design criteria, an engineering analysis may be required based on the use of the design properties accepted in the CCMC 12768-R evaluation report. Design properties are also indicated in table 1 at the front of the design manual. For technical support, contact International Beams (IB) or your local IB distributor. (g) Continuous spans given in the table above are the longest clearspan between bearings for a joist with three bearings. The ratio of the shorter span to the longer spans must be greater than 40%. For two spans with a ratio of between 40% and 76%, provide metal hangers or equivalent to withstand an uplift force at the end of the shorter span. Calculate uplift at the end of the shorter span as follows: factored total load (psf) x joist spacing (inches) x [(shorter span (feet) minus 0.76 x longer span (feet)] divided by 25. For all other applications, consult International Beams.

Floor Framing &Construction DetailsFloor Framing and Construction Details

1. Before laying out floor system components,verify that IB I-joist flange widths matchhanger widths. If not, contact your supplier.

2. Except for cutting to length, never cut, drill,or notch IB I-joist flanges.

3. Install IB I-joists so that top and bottomflanges are within ½ inch of true verticalalignment.

4. IB I-joists must be anchored securely tosupports before floor sheathing is attached,and supports for multiple-span joists mustbe level.

5. Minimum bearing lengths: 1¾ inches forend bearings and 3 ½ inches for intermediatebearings.

6. When using hangers, seat IB I-joists firmlyin hanger bottoms to minimize settlement.

7. Leave a ¹⁄₁₆ inch gap between the IB I-joistend and a header.

8. Concentrated loads greater than those thatcan normally be expected in residentialconstruction should only be applied to thetop surface of the top flange. Normalconcentrated loads include track lightingfixtures, audio equipment and securitycameras. Never suspend unusual or heavyloads from the IB I-joist’s bottom flange.

Whenever possible, suspend allconcentrated loads from the top of theIB I-joist. Or, attach the load to blockingthat has been securely fastened to the IBI-joist webs.

9. Never install IB I-joists where they will bepermanently exposed to weather, or wherethey will remain in direct contact withconcrete or masonry.

10. Restrain ends of floor joists to preventrollover. Use rim board or equivalent,rim joists or IB I-joist blocking panels.

11. For IB I-joists installed over and beneathbearing walls, use full depth blockingpanels, rim board, or squash blocks (cripplemembers) to transfer gravity loads throughthe floor system to the wall or foundationbelow.

12. Due to shrinkage, common framinglumber set on edge may never be used asblocking or rim boards. IB I-joist blockingpanels or other engineered wood products– such as rim board – must be cut to fitbetween the IB I-joists, and an IB I-joist-compatible depth selected.

13. Provide permanent lateral support of thebottom flange of all IB I-joists at interior

supports of multiple-span joists. Similarly,support the bottom flange of allcantilevered IB I-joists at the end supportnext to the cantilever extension. In thecompleted structure, the gypsum wallboardceiling provides this lateral support. Untilthe final finished ceiling is applied,temporary bracing or struts must be used.

14. If square-edge panels are used, edges mustbe supported between IB I-joists with 2x4blocking. Glue panels to blocking tominimize squeaks. Blocking is not requiredunder structural finish flooring, such aswood strip flooring, or if a separateunderlayment layer is installed.

15. Nail spacing:• Space nails installed to the flange’s top

face in accordance with the applicable building code requirements or approvedbuilding plans.

• If nails must be installed into the sides of flanges, spacing shall not be closer than 3 inches o.c. for 8d common nails, and 4 inches o.c. for 10d common nails.

Web StiffenerRequirementsA web stiffener is a wood block that is usedto reinforce the web of an IB I-joist atlocations where:

• The webs of the IB I-joists are in jeopardyof buckling out of plane. This usuallyoccurs in deeper IB I-joists.

• The webs of the IB I-joist are in jeopardyof “knifing” through the IB I-joist flanges.This can occur at any IB I-joist depth whenthe design reaction loads exceed a specificlevel.

• The IB I-joist is supported in a hanger and the sides of the hanger do not extend up to the top flange. With the topflange unsupported by the hanger sides,the joist may deflect laterally, putting atwist in the flange of the joist. The webstiffener supports the IB I-joist along avertical axis as designed. (In this application,the web stiffener acts very much like abacker block.)

There are two kinds of web stiffeners:bearing stiffeners and load stiffeners. Theyare differentiated by the applied load and

location of the gap between the slightlyundersized stiffener and the top or bottomflange.

Bearing stiffeners are located at thereactions, both interior and exterior, whenrequired. IB I-joists do not need bearingstiffeners at any support when subjectedto normal residential form loads andinstalled in accordance with the allowablespans.

Load stiffeners are located betweensupports where significant point loads areapplied to the top flange of an IB I- joist.

Web stiffener blocks may be comprised oflumber, rim board, or structural woodpanels. The minimum grade of structuralwood panels is Rated Sheathing;minimum lumber grade is Utility gradeSPF (south) or better. Any rim boardproduct would also work satisfactorily.Ideally, the depth of the web stiffenershould equal the distance between theflanges of the joist minus ⅛ inch -¼ inch. For bearing stiffeners, this gap is

placed between the stiffener and thebottom of the top flange. For loadstiffeners, the gap is located at the bottomof the stiffener.

1. A bearing stiffener is required in allengineered applications which exceedthe "no stiffeners" factored reactionresistances indicated in table 1A onpage 4. The gapbetween the stiffener and the flange is atthe top. 2. A load stiffener is required at locations where a concentrated load greater than1500 lb. unfactored load is applied to the top flange between supports, or in the case of acantilever, anywhere between thecantilever tip and the support. The gapbetween the stiffener and the flange is atthe bottom. 3. A bearing stiffener is required when theIB I-joist is supported in a hanger and thesides of the hanger do not extend up to,and support, the top flange. The gapbetween the stiffener and flange is at top.

Typical Holes

Allowable Webhole Sizes and Locations

Minimum Distance, D, from Inside Face of Any Support to Center of Web Hole (Simple or Multi-span)

IB I-joist top and bottom flanges must never be cut, notched, or otherwise modified.Holes in web should be cut with a sharp saw. For rectangular holes, avoid over-cutting the corners,as this can cause unnecessary stress concentrations. Slightly rounding the corners is recommended.Starting the rectangular hole by drilling a 1" diameter hole in each of the 4 corners and thenmaking the cuts between the holes is another good method to minimize damage to I-joist.

Notes:

1. Table may be used for I-joist spacing 24 inches on center or less.

2. Hole location distance is measured from inside face of supports to center of hole.

3. Distances in this chart are based on uniformly loaded joists.

4. Joists with web hole location and/or sizes that fall outside of the scope of this table must be analyzed based on the actual hole size, joist spacing, span and loading condition. The I-joist shear capacity at the location

of the circular web hole is calculated using the following equation: V(round hole)

= Published Shear Value x [(Joist Depth - Hole Diameter) / Joist Depth.

SAF = Span adjustment factor, used as defined below

OPTIONAL: This table is based on I-joists being used at their maximum span. If the I-joists are placed at less than their full allowable span, the maximum distance from the centerline of the hole to the face of any support (D), as given above may be reduces as follows:

Dreduced = Lactual/SAF x D

Where:

Dreduced

= Distance from the inside face of any support to center of hole, reduced for less than maximum span applications (ft). The reduced distance must not be less than 6-inches from the face of support to edge of hole

Lactual

= The actual measured span distance between the inside faces of supports (ft)

SAF = Span Adjustment Factor given above

D = The minimum distance from the inside face of any support to center of hole given above.

If Lactual

/SAF is greater than 1, use 1 in the above calculation for Lactual

/SAF

5. I-joist top and bottom flanges must NEVER be cut, notched, or otherwise modified.

6. Whenever possible field-cut holes should be centered on the middle of the web.

7. The maximum size hole that can be cut into an I-joist web shall equal the clear distance between the flanges of the I-joist minus 1/4 inch.

A minimum of 1/8 inch should be maintained between the top or bottom of the hole and the adjacent I-joist flange.

8. The sides of square holes or longest sides of rectangular holes should not exceed three fourths of the diameter of the maximum round hole permitted at the location.

9. Where more than one hole is necessary, the distance between adjacent hole edges shall exceed twice the diameter of the largest round hole or twice the size of the largest square hole (or twice the length of the longest side of

the longest rectangular hole) and each hole must be sized and located in compliance with the requirements of the table above.

10. A knockout is not considered a hole, may be utilized anywhere it occurs and may be ignored for purposes of calculating minimum distances between holes.

11. 1-1/2" holes shall be permitted anywhere in a cantilevered section of an IB Joist. Holes of greater size may be permitted subject to verification.

12. A 1-1/2" hole can be placed anywhere in the web provided that it meets the requirements of 6 above.

13. For joists with more than one span, use the longest span to determine hole location in either span.

14. All holes shall be cut in a workman-like manner in accordance with the restrictions listed above and as illustrated in figure above.

15. A group of round holes at approximately the same location shall be permitted if they meet the requirements for a single round circumscribed around them.

16. Refer to International Beams Design Software for other hole sizes and locations.

DiscussionFire and sound rated assemblies are required for multi-family residential and commercial buildings. Both floor/ceiling and wall

separation assemblies may be required. A townhouse may only require a 45 minutes fire-rated floor/ceiling separation assembly, but

multi-family residential and commercial buildings require a fire rating of one hour (two hours for some commercial buildings). A

roof/ceiling fire-rated assembly may also be required. A minimum sound transmission class (STC) rating of 50 is required for

multi-family and commercial buildings under the National Building Code of Canada (NBCC-2005 edition). The specified assembly

must meet both the fire rating and STC sound rating minimum requirements. Although impact insulation class (IIC) sound ratings

are not a requirement of NBCC, data is available for design. A target minimum IIC sound rating of 50 is recommended for design.

International Beams I-joists are listed with Intertek Testing Service (ITS), an accredited test lab and listing service recognized by the Standards Council of Canada and NBCC-2005. This ITS listing adopts by reference all of the generic fire and sound rated assemblies which include I-joists in Table A-9.10.3.1.B of NBCC-2005 edition. The ITS 1-hour fire-rated floor/ceiling assembly 60.02 example below, most closely matches assembly number F11g in the NBCC table of generic assemblies.

Roof Installation Guidelines

Roof Framing &Construction Details

1. Installation of IB I-joists must be as shown indetails 2A- 2L.

2. Except for cutting to length, or for providingbirdsmouth bearings as detailed in detail 2H,IB I-joist top or bottom flanges should NEVERbe cut, drilled or notched.

3. IB I-joists are permitted to be birdsmouth cutat the lower end of the joist only. Thebirdsmouth cut must have full bearing andnot overhang the inside face of the plate.Bearing/web stiffeners are required at thebirdsmouth cut on both sides of the web.

4. When beveled bearing plates are used at IBI-joist supports, IB I-joist attachment to thebevel plate must be designed to transfer lateralthrust.

5. Concentrated loads should only be appliedto the top surface of the top flange. At notime should concentrated loads be suspendedfrom the bottom flange, with the exceptionof light loads (lighting fixtures, ceiling fans,etc.).

6. IB I- joists must be protected from the weatherprior to installation.

7. IB I-joists must not be used in places wherethey will permanently exposed to weather(overhangs are exceptionally vulnerable) orin areas where they will reach a moisturecontent greater than 16%, such as in a

swimming pool or hot-tub enclosure. Theymust not be installed where they will be in directcontact with concrete or masonry.

8.

9. Ends of roof joists must be restrained at thebearing to prevent rollover. Rim board orIB I-joist blocking panels are preferred.Cantilever-end blocking must be placed atthe support adjacent to the cantilever, andends of all cantilever extensions must belaterally braced by a fascia board or othersimilar method.

10. Rim board, IB I-joist blocking panels, or othermeans of providing lateral support must beprovided at all IB I-joist bearing points.

11. Continuous lateral support of the IB I-joist'scompression flange is required to preventrotation and buckling. In simple span roofapplications, lateral support of the top flangeis normally supplied by the roof sheathing.Bracing of the IB I- joist’s bottom flange is alsorequired at interior supports of multiple-spanjoists and at the end support next to an

overhang. Lateral support of the entire bottomflange may be required in cases of load reversalsuch as those caused by high wind.

12. Nails installed perpendicular to the wide faceof the flange must be spaced in accordancewith the applicable building coderequirements or approved building plans butshould not be closer than 3 in. o.c.per row using 8d common nails.

13.

14. The top and bottom flanges of the IB I-joistmust be kept within½ in. of true alignment.The use of IB I-joist blocking panels or engineered wood rim board greatlysimplifies this requirement.

15. All roof details are valid up to 12:12 slopeunless otherwise noted.

Notes:

1. Allowable clear span applicable to simple-scan roof construction with unfactored design snow and dead load as specified. The maximum span is based on the horizontal distance between centerline of supports.2. The strength limit states are based on the factored loads of 1.50L + 1.25D. The serviceability limit states include the consideration of unfactored live load deflection limit of L/360 (with plaster or gypsum board ceiling) OR L/240 (suspended ceiling or other). Total load deflection limit is based on unfactored total load at L/180 deflection criteria.3. Additional considerations: NO composite action with the sheating; NO vibration analysis; Alternate limit state of 20 psf net wind uplift normal to the surface with L/360 live load deflection limit.4. Spans include a cantilever of up to 24" at one end of the IB I-joist.5. Minimum bearing length shall be 1¾" for end bearing and 3½" for bearing adjacent to cantilever.6. Bearing stiffeners are not required when I-joists are used with the spans given in this table, except as required by hanger manufacturers.7. This span table is based on uniform loads and Limit State Design (LSD) per CSA 086-01. For applications with other than uniformly distributed loads, or other applications beyond the scope of the indicated design criteria, an engineering analysis may be required based on the use of the design properties accepted in the CCMC 12768-R evaluation report. Design properties are also indicated in table 1 at the front of the design manual. For technical support, contact International Beams (IB) or your local IB distributor.
