> This Bulletin applies only to the structural features of this method
> of construction. Final determination of eligibility is made by the
> appropriate HUD Field Office. Other factors considered by the Field
> Office will be valuation, location, architectural planning and appeal,
> mechanical equipment, thermal characteristics, and market acceptance.
> Consideration is also necessary to determine whether a specific
> property will qualify under the specific HUD program, when constructed
> according to the method outlined in this Bulletin, and where the
> structure is to be located.
>

>
> Compliance with HUD MPS will be determined by the HUD Field Office or
> Homeownership Center on the same basis as submissions involving
> conventional construction, except for the special features described
> in this Bulletin.
>
> 4\. Inspection:
>
> Field compliance inspections covering conventional items of
> construction and any special features covered in this Bulletin shall
> be made in accordance with prescribed procedures.
>
> The appropriate HUD Field Office or Homeownership Center shall furnish
> a copy of a HUD field inspection report to Headquarters, FHA
> Standards, Office of Manufactured Housing Programs, when there is:

a.  Evidence of noncompliance with portions of the system of
    construction described in this Bulletin.

> [GENERAL:]{.underline}
>
> This Bulletin provides for the use of NASCOR NJ, NJH & NJU I-Joists,
> an all wood product, developed by NASCOR Ltd., for floor and roof
> spans up to 34 feet and 7 inches.
>
> [PRODUCT DESCRIPTION]{.underline}:
>
> The NASCOR NJ Series I-joists manufactured wood I-joists are available
> in depths of 9^1^/~4~ inches (235 mm), 9^1^/~2~ inches (241 mm), and
> 11^7^/~8~ inches (302 mm). Their flanges are composed of one-piece or
> fingerjoined nominal 2 x 3 inch (51 x 76 mm), No. 2 or better
> spruce-pine-fir (SPF) solid sawn lumber oriented with their 3x
> dimension in the vertical direction. The webs are ^3^/~8~ inch (9.5
> mm) thick oriented strand board (OSB), graded to exceed the
> requirements of Exposure 1, Structural 1 rated, performance rated
> panels (APA PRP-108) United States Department of Commerce (DOC) PS-2
> and/or Canadian Standards Association (CSA) Standard CSA 0325. The
> flanges are routered to accept the web and the section is joined by a
> qualified adhesive.
>
> The NASCOR NJH Series I-joists are similar to the NJ Series I-joist
> except that their flanges are oriented with their 3x dimension in the
> horizontal. NJH Series I-joists are available in depths of 9^1^/~2~
> inches (241 mm), 11^7^/~8~ inches (302 mm), 14 inches (356 mm), and 16
> inches (406 mm).
>
> The NASCOR NJU Series I-joists are similar to the NJ Series I-joist
> except that their flanges are 2 x 4 inch (51 x 102 mm), No. 2 or
> better spruce-pine-fir (SPF) solid sawn lumber oriented with their 4x
> dimension in the horizontal. NJU Series I-joists are available in
> depths of 9^1^/~2~ inches (241 mm), 11^7^/~8~ inches (302 mm), 14
> inches (356 mm), 16 inches (406 mm), and 18 inches (457 mm).
>
> Flange members, web members, and water-resistant glue are fed into a
> machine that assembles the finished product on a continuous basis. The
> I-joist is cut to the desired length as it leaves the machine and is
> stored in a controlled environment to allow the adhesive to cure.
>
> [MANUFACTURING PROCESS FOR NASCOR I-JOIST]{.underline}:
>
> The I-joists are manufactured in a continuous process with the
> following steps:
>
> 1\. Web sections are glued and end-jointed to form a continuous web.
>
> 2\. Flange material is grooved for the web joint.
>
> 3\. While applying a constant uniform flow of glue to the joint, the
> flanges and web are brought together through a series of vertical and
> horizontal rollers which apply continuous pressure to form the beam.

-4-

> Finished I-joist are bundled and wrapped with weatherproof material
> and stored in such a manner as to prevent excessive weathering, glue
> line breakdown or deterioration of the wood components.
>
> [DESIGN AND ERECTION]{.underline}:
>
> Design and erection of NASCOR I-Joists shall be in accordance with
> Attachment "A". A hole chart defining the maximum size and
> corresponding positions of permissible holes in web members is also
> including in Attachment "A". When I-joists are used as simple-span
> members, the design shear is equal to the end reaction.
>
> [LOAD TABLES]{.underline}:

> Notes on Table 1:

1.  Mid-span deflection of simply supported joists shall be calculated
    using the following equations:

> = [5 W L^4^]{.underline} + [W L^2^]{.underline} for Uniform Loads
>
> 384 EI K
>
> = [PL^3^]{.underline} + 2[PL]{.underline} for Concentrated Loads at
> mid-span
>
> 48EI K
>
> Where: W = Uniform load in pounds per linear inch
>
> P = Concentrated load in pounds
>
> L = Span in inches
>
> EI = Joist Stiffness in lbs-in^2^ from (table 1)
>
> K = Shear deflection shear constant in pounds (from table 1)

2.  Allowable shear may be further limited by the allowable end
    reaction, depending on the joist type and bearing length selected.

3.  Joist flanges are No. 2 or better SPF. Web material is 3/8 inch
    thick OSB.

A.  MULTIPLE HOLES

    -   The spacing required between the edges of round holes must be a
        minimum of 2-1/2 times the diameter of the largest hole.

    -   The spacing required between the edges of rectangular holes must
        be a minimum of 5 times the width (distance parallel to flange)
        of the largest rectangular hole.

    -   The spacing required between the edges of a round hole and a
        rectangular hole must be 5 times the width of the largest
        rectangular hole or 5 times the diameter of the round hole,
        whichever is greater.

B.  ROUND HOLES (Refer to Tables 5 - 10 for locations and spans)

-   A 1 ½" diameter hole can be drilled anywhere in the web except over
    a support.

-   All holes must leave a minimum of ¼" of uncut web above and below
    the hole.

    A.  RECTANGULAR HOLES (Refer to Tables 5 - 10 for locations and
        spans)

        -   The holes must be centered vertically in the web.

        -   Cutting a radius on the corners of a rectangular hole is
            recommended.

        -   The maximum allowable hole width (distance parallel to the
            flanges) shall be 1-1/2 times the hole depth.

    B.  GENERAL

        -   No holes are allowed over a support.

        -   Do not cut or nick the flanges when cutting holes in web.

        -   A minimum distance of ¼" is required between the edge of the
            hole and the flange.

        -   Valid for simply supported spans where uniform distributed
            loads do not exceed 40 psf live and 25 psf dead.

        -   Multiple maximum size holes may not be possible for some
            joist types. Check required distance from edge of

> nearest support to hole and the required spacing between holes.

> Notes on Table 4:

1.  Table is applicable for single span, simply supported joists
    subjected to the uniform loads indicated in the table.

2.  Spans are based on composite action of glued and nailed sheathing.
    Spans must be reduced by 12 inches where sheathing is nailed only.

3.  Live load deflection is limited to L/360 and total load deflection
    limited to L/240.

4.  Minimum bearing length of 1½ inches is required, unless otherwise
    noted.

5.  Minimum bearing length of 2½ inches is required.

6.  Web holes are permitted as outlined in Figure 1.

7.  7% repetitive member increase is included.

> Notes on Table 5:

1.  Table is based on a maximum uniform floor loading of 40 psf live and
    25 psf dead load.

2.  Table is applicable for joist spacings of 24 inches on center or
    less.

3.  Joist span is based on the clear span, distance from inside of the

> Notes on Table 6:

1.  Table is based on a maximum uniform floor loading of 40 psf live and
    25 psf dead load.

2.  Table is applicable for joist spacings of 24 inches on center or
    less.

3.  Joist span is based on the clear span, distance from inside of the
    end supports.

4.  Hole location is the distance measured from the inside face of the
    nearest support to the centerline of the hole.

5.  The maximum hole depth must leave ¼ inches minimum of web material
    between the top and bottom of the hole and the flange.

> Notes on Table 9:

1.  Table is based on a maximum uniform floor loading of 40 psf live and
    25 psf dead load.

2.  Table is applicable for joist spacings of 24 inches on center or
    less.

3.  Joist span is based on the clear span, distance from inside of the
    end supports.

4.  Hole location is the distance measured from the inside face of the
    nearest support to the edge of the hole.

5.  The maximum hole depth must leave ¼ inches minimum of web material
    between the top and bottom of the hole and the flange.

6.  The maximum allowable hole width (distance parallel to flange) shall
    be 1-1/2 times the hole depth.

> Notes on Table 10:

1.  Table is based on a maximum uniform floor loading of 40 psf live and
    25 psf dead load.

2.  Table is applicable for joist spacings of 24 inches on center or
    less.

3.  Joist span is based on the clear span, distance from inside of the
    end supports.

4.  Hole location is the distance measured from the inside face of the
    nearest support to the centerline of the hole.

5.  The maximum hole depth must leave ¼ inches minimum of web material
    between the top and bottom of the hole and the flange.
