WoodWorks analysis and design are in accordance with the ICC International Building Code (IBC 2012), the National <br />Design Specification (NDS 2012), and NDS Design Supplement. <br />2. Please verify that the default deflection limits are appropriate for your application. <br />3. Continuous or Cantilevered Beams: NDS Clause 4.2.5.5 requires that normal grading provisions be extended to the <br />middle 2/3 of 2 span beams and to the full length of cantilevers and other spans. <br />4. Sawn lumber bending members shall be laterally supported according to the provisions of NDS Clause 4.4.1. <br />· 5. SLOPED BEAMS: level bearingis required for atl sloped beams. <br />6. The critical deflection value has been determined using maximum back-span deflection. Cantilever deflections do not <br />govern design.
