Skaggs, PhD, PE<br \/>\n<\/strong>Engineered wood products are specified for a wide range of light-frame floor assemblies in light commercial and multi-family construction. I-joists, glued-laminated timber (glulam), rim board, laminated veneer lumber (LVL), laminated strand lumber (LSL), and oriented strand lumber (OSL) are popular due to their availability, precision, strength, and consistent quality.<\/p>\n<p>As use of these products expands beyond conventional construction, engineers and specifiers are raising questions concerning the use of I-joists and rim board around the perimeter of the structure, where the wood floors are designed as diaphragms and the walls above are designed \u2028as shear walls.<\/p>\n<p>In these applications, the engineered wood product forming the rim joist\/board around a floor system is subject to numerous loads not normally considered in conventional, non-engineered applications. These additional factors include:<\/p>\n<ul>\n<li>\u2028transfer of shear wall forces from the walls above into the foundation\/wall framing below;<\/li>\n<li>\u2028diaphragm perimeter nailing; and<\/li>\n<li>\u2028shear transfer of diaphragm loads to the foundation\/wall framing below.<\/li>\n<\/ul>\n<p>Such design forces create attachment requirements that exceed normal fastening requirements found in the building codes. The designer\u2019s challenge is to detail these critical connections in order to transfer the applied loads through the connection economically and efficiently. One should consider that rim boards and I-joists may be used in rim joist applications, offering predictable performance and consistent quality. (Attachment considerations vary.)<\/p>\n<p><strong>Rim board<br \/>\n<\/strong>The <em>International Building Code<\/em> (<em>IBC<\/em>) is consistent in prescriptively requiring rim joists to be attached to structural framing below with 8d 3.3 x 63-mm (0.131 x 2 \u00bd-in.) common toe nails spaced at 150 mm (6 in.) on center (oc) for conventional construction.<\/p>\n<p>While this attachment schedule is sufficient to develop a lateral load capacity of 2.63 to 2.92 kN\/m (180 to 200 lbf\/ft)\u2014as required for the conventional <em>IBC<\/em> construction provisions\u2014it falls short of developing the actual lateral load capacity of the rim joist products, which exceeds 14.59 kN\/m (1000 lbf\/ft).<\/p>\n<p>One should be cautious when attempting to increase shear-transfer capacities of the rim joist by spacing toe nails closer than 150 mm oc. Closer spacing may cause splitting in some rim joist products, and an increased lateral load capacity may not be achieved using this technique. Instead, one should consider using framing anchors or blocking to develop the additional lateral capacity required when using rim boards for transferring shear loads through floors.<\/p>\n<p><strong>I-joists<br \/>\n<\/strong>I-joists may be used as rim joists at diaphragm perimeters. By virtue of their flanges, toe nails are rendered unnecessary, making I-joists easier to attach to structural framing above and below the joist.<\/p>\n<p>However, because flanges in some I-joist configurations may split with close nail spacing, the diaphragm lateral load capacities are limited by the minimum nail spacing recommended by the I-joist manufacturer. In some cases, staggered nailing may be necessary to develop the full diaphragm lateral load capacities.<\/p>\n<p><strong>Preventing incompatibilities<br \/>\n<\/strong>Some design professionals may be surprised to learn that they should never mix engineered wood products and sawn lumber in a roof or floor system without careful analysis of the potential consequences.<\/p>\n<p>Engineered wood products are manufactured at very low moisture contents (<em>i.e. <\/em>five percent or lower) and with a high degree of dimensional accuracy. On the other hand, sawn lumber products are sized and sold at moisture contents often exceeding 16 percent. When used together on a jobsite, the engineered wood products may expand due to increased moisture content, while the sawn lumber products may shrink as they dry. In situations where lumber and engineered wood products are used together and are intended to \u2018share\u2019 vertical loads in floor or roof systems, this differential shrinkage \u2028can lead to situations that must be carefully considered.<\/p>\n<p>There are applications, such as diaphragm, \u2018squash,\u2019 backer, or filler blocking, where sawn lumber may be used in conjunction with engineered wood products. In these applications, the sawn lumber member either does not carry vertical loads or is used in such a way the load is applied to the end grain in specifically sized members.<!--nextpage--><\/p>\n<div class=\"wonderpluginslider-container\" id=\"wonderpluginslider-container-25\" style=\"max-width:800px;margin:0 auto;padding-left:0px;padding-right:0px;padding-top:84px;padding-bottom:0px;\"><div class=\"wonderpluginslider\" id=\"wonderpluginslider-25\" data-sliderid=\"25\" data-width=\"800\" data-height=\"400\" data-skin=\"topcarousel\" data-autoplay=\"false\" data-randomplay=\"false\" data-loadimageondemand=\"false\" data-transitiononfirstslide=\"false\" data-autoplayvideo=\"false\" data-isresponsive=\"true\" data-fullwidth=\"false\" data-isfullscreen=\"false\" data-ratioresponsive=\"false\" data-showtext=\"true\" data-showtimer=\"true\" data-showbottomshadow=\"false\" data-navshowpreview=\"false\" data-textautohide=\"false\" data-lightboxresponsive=\"true\" data-lightboxshownavigation=\"false\" data-lightboxshowtitle=\"true\" data-lightboxshowdescription=\"false\" data-texteffectresponsive=\"true\" data-donotinit=\"false\" data-addinitscript=\"false\" data-lightboxfullscreenmode=\"false\" data-lightboxcloseonoverlay=\"true\" data-lightboxvideohidecontrols=\"false\" data-lightboxnogroup=\"false\" data-triggerresize=\"false\" data-lightboxautoslide=\"false\" data-lightboxshowtimer=\"true\" data-lightboxshowplaybutton=\"true\" data-lightboxalwaysshownavarrows=\"false\" data-lightboxshowtitleprefix=\"true\" data-titleusealt=\"false\" data-outputtext=\"false\" data-scalemode=\"fit\" data-arrowstyle=\"mouseover\" data-transition=\"fade\" data-loop=\"0\" data-border=\"0\" data-slideinterval=\"8000\" data-arrowimage=\"arrows-48-48-4.png\" data-arrowwidth=\"48\" data-arrowheight=\"48\" data-arrowtop=\"50\" data-arrowmargin=\"0\" data-navstyle=\"thumbnails\" data-navimage=\"bullet-24-24-5.png\" data-navwidth=\"109\" data-navheight=\"72\" data-navspacing=\"4\" data-navmarginx=\"16\" data-navmarginy=\"-84\" data-navposition=\"top\" data-playvideoimage=\"playvideo-64-64-0.png\" data-playvideoimagewidth=\"64\" data-playvideoimageheight=\"64\" data-lightboxthumbwidth=\"90\" data-lightboxthumbheight=\"60\" data-lightboxthumbtopmargin=\"12\" data-lightboxthumbbottommargin=\"4\" data-lightboxbarheight=\"64\" data-lightboxtitlebottomcss=\"color:#333;

In these applications, the floor sheathing\u2014normally wood structural panels\u2014is attached to the floor perimeter framing with 8d 3.3 x 63-mm nails at 150 mm oc. In engineered applications, the design loads and geometry of the structure may dictate a diaphragm perimeter nailing schedule of 100 or\u2028150 mm oc or less.<\/p>\n<p>Performance of some engineered wood products, such as rim joists, can be adversely impacted by a closer nail spacing schedule. In such applications, \u2028it is important to accommodate these loads and their corresponding close nailing schedules without compromising the integrity of the rim joist.<\/p>\n<p><em>Shear transfer of diaphragm loads to the foundation\/wall framing below<br \/>\n<\/em>When Detail A1 or A2 is used to transfer higher diaphragm shear values into the diaphragm perimeter framing (the rim joist), the attachment schedule at the base of the framing must be adjusted to accommodate the additional load into the foundation or framing below. Minimum nailing recommendations for rim board to framing connections published in the model building codes are insufficient to transfer the additional diaphragm loads that precipitated the use of 50, 65, or 100 mm (2, 2 1\u20442, or 4 in.) oc diaphragm perimeter nailing schedules.<\/p>\n<p>One should take care to prevent splitting the framing members when specifying additional fasteners. Additionally, nail and lumber specifications must provide for a minimum depth of penetration allowing full connection capacity.<\/p>\n<p>Figure 1 illustrates methods that may be used in order to accommodate the project\u2019s diaphragm perimeter nailing requirements.<\/p>\n<p>Figure 2 shows Details B1 through B4 providing examples of methods used to accommodate these loads at the base of the rim joist.<\/p>\n<p><em>Transfer of shear wall forces from the walls above into the foundation\/wall framing below<br \/>\n<\/em>In engineered construction, lateral loads are transferred from the roof and floor diaphragms through the shear walls and eventually into the foundation. Most wood structures are now platform-framed (<em>i.e.<\/em> the interior and exterior walls sit on the floor below), and special detailing is required to transfer the forces from the shear walls above to the walls or foundation below. However, it is not always possible to transfer these forces from a shear wall above directly to the rim board below because of the possibility of splitting the framing materials forming the rim board.<\/p>\n<p>For this reason, APA\u2013The Engineered Wood Association shows various methods to safely transfer forces around this critical connection. In Figure 3 (page 66), the details provide for all shear panel edges to occur over and be attached to common framing, subject to fastener limitations specified by the I-joist manufacturer. If connections are made at the web of the I-joist or at a rim board, one should attach backer blocking to ensure minimum nail penetration into the framing; 8d shear nailing requires 35 mm (1 3\u20448 in.) while 10d nailing requires 38 mm (1 1\u20442 in.).<\/p>\n<p>Similar attachment must be provided in areas when shear-transfer nailing from the shear walls above is not accommodated by the fastener details described in C1 and C2. Detail C3 shows the transfer of shear wall forces \u2018around\u2019 the floor diaphragm to rim board connection and directly into the rim board. At the bottom of the rim board, additional nailing is required to transfer the shear wall forces into the foundation below. In C4 and C5, these shear wall forces are transferred directly into the sill plate.<\/p>\n<p><em>Framing anchors<br \/>\n<\/em>In addition to the direct attachment methods, framing anchors may also be used to transfer forces between the various elements of the structural frame. If it is necessary to nail into I-joist LVL flanges parallel to the gluelines when installing framing anchors, one should check with the I-joist manufacturer for nailing limitations.<\/p>\n<p><strong>Design example<br \/>\n<\/strong>An engineer is tasked with designing a two-story, platform-framed wood structure with a tile roof. Since the structure is located in an area of high seismicity (seismic design category [SDC] D2) and because of the mass of the roof, the shear walls sitting on the second floor have a design requirement of 5.55 kN\/m (380 lbf\/ft). The shear load along the edge of the second floor diaphragm parallel to the shear wall in question is 2.55 kN\/m (175 lbf\/ft) in the direction under consideration.<\/p>\n<p>Since the capacity of the rim board with minimum code-required nailing is 2.63 kN\/m (180 plf), no additional fastening is required or permitted at the perimeter of the diaphragm along this edge.<\/p>\n<p>In the example, the engineer selected oriented strand board (OSB) from the 7\u204416 Performance Category (11-mm [7\u204416-in.]) for use as wall sheathing. No additional load can be applied to that connection because all of the capacity at the floor sheathing to rim board available to transfer the diaphragm shear has been effectively utilized. As such, the engineer uses the wall sheathing to transfer the shear wall forces \u2018around\u2019 the rim board, utilizing one of the methods shown in Detail C2, Option 4 (Figure 3).<\/p>\n<p>The shear walls are attached with 8d common nails. The engineer decides to use this same size nail to transfer the shear stresses between floors:<\/p>\n<ol>\n<li>\u2028With 7\u204416 Performance Category OSB wall sheathing (a side member 11 mm [7\u204416 in.] thick) and a main member consisting of two layers of 28.5-mm (1 1\u20448-in.) Performance Category OSB rim board (where a penetration depth of 34 mm [1 3\u20448 in.] is required to develop the nail capacities), an unadjusted single nail has a capacity of 460 N (103 lbf) per nail.<\/li>\n<li>\u2028The number of fasteners required equals 5.55\/460 x 1000 equals 12.11 fasteners per meter (3.69 per ft).<\/li>\n<li>\u2028The distance between fasteners equals 1000\/12 equals 83 mm, 3.25 in. (12\/3.69 equals 3.25).<\/li>\n<li>\u2028Therefore, one should use 75 mm (3 in.) oc both above and below the OSB wall sheathing joint at the double rim board.<\/li>\n<\/ol>\n<p>With proper detailing, engineers and specifiers can safely and cost-effectively transfer shear loads from walls above into the foundation and walls below.
