Listed span for "Double Span" tables is the distance from either <br />end to the center of interior support, with the stud continuous <br />past the interior support. <br />2. Listed wind pressures represent calculated designed wind <br />pressure (1.0 W based on 2009 or 0.6 W based on 2012 IBC or <br />later ASD load combinations). For deflection calculations, listed <br />wind pressures have been reduced by 0.70 as allowed by IBC. <br />The 5 psf pressure has not been reduced for deflection checks. <br />3. Studs must be braced against rotation and lateral movement at <br />all supports. See typical bracing details on page 61. <br />4. Studs are assumed to be adequately braced at a maximum <br />spacing of L u to develop full allowable moment. <br />5. Web crippling check is based on 1" of bearing at end supports <br />and 3" of bearing at interior support. <br />6. Shear and web crippling capacity at end supports have not been <br />reduced for punchouts. Shear and web crippling capacity at <br />interior support have been reduced for the presence of punchout <br />adjacent to the support. <br />7. Combined bending and shear check at interior support is based <br />on unreinforced web per AISI S100 (Eq. C3.3.1-1). Shear capacity <br />and combined bending and shear check at interior support have <br />been reduced for the presence of punchouts adjacent to support. <br />8. See page 5 for additional table notes.
