F' theta calculated fof e,#ch support <br />as per NDS 3.10.3 <br />Design Notes: <br />1. WoodWorks analysis and design are in accordance with the ICC International Building Code (IBC 2012), the'National <br />Design Specification (NDS 2012), and NDS De5ign 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 bearing is required for all sloped beams. <br />6. The critical deflection value has been determined using maximum back-span deflection. Cantilever deflections do not <br />govern design.
