<br />a. Spans are given in feet and inches.
<br />b. Tabulated values assume #2 grade lumber.
<br />c. Building width is measured perpendicular to the ridge. For widths between
<br />those shown, spans are permitted to be interpolated.
<br />d. NJ - Number of jack studs required to support each end. Where the number of
<br />required jack studs equals one, the header is permitted to be supported by an
<br />approved framing anchor attached to the full -height wall stud and to the
<br />header.
<br />R502.2.6 Bearing. The ends of each joist, beam or girder shall have not less than 1.5 inches (38 mm)
<br />of bearing on wood or metal and not less than 3 inches (76 mm) on masonry or concrete except where
<br />supported on a 1-inch-by-4-Inch (25.4 mm by 102 mm) ribbon strip and nailed to the adjacent stud or
<br />by the use of approved joist hangers.
<br />R502. 2.6. 1 Floor systems [ IRC R502. 6. 1]. Joists framing from opposite sides over a bearing support
<br />shall lap a minimum of 3 inches (76 mm) and shall be nailed together with a minimum three 10d face
<br />nails. A wood or metal splice with strength equal to or greater than that provided by the nailed lap
<br />is permitted.
<br />R502.2.6.2 Joist framing [IRC R502.6.2]. Joists framing into the side of a wood girder shall be
<br />supported by approved framing anchors or on ledger strips not less than nominal 2 inches by 2 inches
<br />(51 mm by 51 mm).
<br />R502.2.7 Lateral restraint at supports [IRC R502.7]. Joists shall be supported laterally at the ends
<br />by full -depth solid blocking not less than 2 inches (51 mm) nominal in thickness; or by attachment to
<br />a full -depth header, band, or rim joist, or to an adjoining stud; or shall be otherwise provided with
<br />lateral support to prevent rotation.
<br />Exception: Reserved.
<br />R502. 2. 7. 1 Bridging [ IRC R502. 7. 1]. Joists exceeding a nominal 2 inches by 12 inches (51 mm by 305 mm)
<br />shall be supported laterally by solid blocking, diagonal bridging (wood or metal), or a continuous
<br />1-Inch-by-3-inch (25.4 mm by 76 mm) strip noiled across the bottom of joists perpendicular to joists
<br />at intervals not exceeding 8 feet (2438 mm).
<br />R502.2.8 Drilling and notching [IRC R502.8]. Structural floor members shall not be cut, bored or
<br />notched In excess of the limitations specified in this section. See Figure R502.2.8.
<br />R502. 2. 8. 1 Sawn lumber[ IRC R502. 8. 1]. Notches in solid lumber joists, rafters and beams shall not
<br />exceed one -sixth of the depth of the member, shall not be longer than one-third of the depth of the
<br />member and shall not be located in the middle one-third of the span. Notches at the ends of the member
<br />shall not exceed one-fourth the depth of the member. The tension side of members 4 inches (102 mm) or
<br />greater in nominal thickness shall not be notched except at the ends of the members. The diameter of
<br />holes bored or cut into members shall not exceed one-third the depth of the member. Holes shall not be
<br />closer than 2 inches (51 mm) to the top or bottom of the member, or to any other hole located in the
<br />member. Where the member is also notched, the hole shall not be closer than 2 inches (51 mm) to the
<br />notch.
<br />R502.2.8.2 Engineered wood products [IRC R502.8.2]. Cuts, notches and holes bored in trusses,
<br />structural composite lumber, structural glue -laminated members or I -joists are prohibited except where
<br />permitted by the manufacturer's recommendations or where the effects of such alterations are
<br />specifically considered in the design of the member by a registered design professional.
<br />R502.2.9 Fastening [IRC R502.9]. Floor framing shall be nailed In accordance with Table R602.2(1)
<br />Where posts and beam or girder construction is used to support floor framing, positive connections
<br />shall be provided to ensure against uplift and lateral displacement.
<br />R502.2.10 Framing of openings [IRC R502. 10]. Openings in floor framing shall be framed with a header
<br />and trimmer joists. When the header joist span does not exceed 4 feet (1219 mm). the header joist may
<br />be a single member the some size as the floor joist. Single trimmer joists may be used to carry a
<br />single header joist that is located within 3 feet (914 mm) of the trimmer joist bearing.
<br />When the header joist span exceeds 4 feet (1219 mm), the trimmer joists and the header joist shall be
<br />doubled and of sufficient cross section to support the floor joists framing into the header. Approved
<br />hangers shall be used for the header joist to trimmer joist connections when the header joist span
<br />exceeds 6 feet (1829 mm). Tail joists over 12 feet (3658 mm) long shall be supported at the header by
<br />framing anchors or on ledger strips not less than 2 inches by 2 inches (51 mm by 51 mm).
<br />R502.3 Design and construction where wind speed is 100 mph or greater. Floor framing of light -frame
<br />wood construction shall be designed and constructed in accordance with the provisions of Section
<br />R301.2. 1.1, Section R502. 1.
